Choosing between a head that never changes shape and one that opens on impact is the broadhead decision that trips up most first-time crossbow hunters. This guide explains how fixed blade broadheads are built, how a fixed-blade broadhead behaves on a crossbow, what you give up and gain against a mechanical head, and how to tune and maintain one so it flies where you aim. If you want specific heads to buy, my best crossbow broadheads guide covers the mechanical heads I have tested. This page does not rank fixed-blade heads; the right fixed head for you is the one that groups with your field points at your crossbow's speed.
It is written for crossbow owners who hunt where it is legal, and it stays on equipment and ethics. Always check current local regulations before you hunt, because some jurisdictions restrict head types, cutting diameters or hunting devices.
What Is a Fixed-Blade Broadhead?
A fixed blade hunting broadhead has its cutting blades set in their final position. Nothing deploys, unfolds or triggers on impact. What you see in your hand is what strikes the animal. That simplicity is the appeal: a fixed-blade head cannot fail to open, cannot open early in the quiver or during carry, and cannot jam partway open the way a mechanical head occasionally can.
The tradeoff is that fixed blades usually cut a smaller diameter than a mechanical head of the same weight. Their exposed edges also add air resistance in flight, so point of impact can drift further from your field points than a well-designed mechanical head flying closed. Neither tradeoff rules them out. They are the other side of the reliability fixed blades offer.
How They Cut and Fly
One-Piece and Replaceable-Blade Designs
Most fixed-blade broadheads use one of two constructions. A one-piece design machines the ferrule and blades from a single piece of steel. That makes it strong and lets you resharpen the edge for years. A replaceable-blade design uses a ferrule body with slot-in blades held by a bushing or collar. Each blade is less durable, but a dull or damaged set swaps out in seconds without a sharpening kit.
Two-Blade, Three-Blade, and Four-Blade Configurations
A two-blade fixed head is commonly reported to fly cleanly and penetrate deeply, because it presents the least cross-section to tissue and bone. A three- or four-blade head can give up some penetration in exchange for a wider cut and an easier blood trail. Neither is objectively correct. Choose for penetration on a quartering shot, or for a more visible blood trail on a broadside shot in thick cover. If low-light tracking is your main concern, lighted bolts can help with any blade count. If you shoot a compatible Ravin crossbow, our tested Ravin R133 lighted arrows are built for that; they are Ravin-specific, so confirm compatibility.
Single-Bevel vs. Double-Bevel Edges
A double-bevel edge is sharpened equally on both sides and is the more forgiving choice for most crossbow hunters. A single-bevel edge is sharpened on one side only, so it rotates as it passes through the animal. Some hunters believe this improves tissue separation on tougher, larger-boned game. Single-bevel heads need more care with head alignment and bolt choice to fly well, so they are an advanced option, not a first broadhead.
Fixed vs Mechanical Broadheads
| Factor | Fixed blade | Mechanical |
|---|---|---|
| Moving parts | None | Blades, locks, bands or clips |
| Typical cutting diameter | Smaller, often 1 to 2 inches | Larger; Nemesis reaches 3.75 in total |
| Flight vs. field points | Needs more tuning checks | Often closer when flown closed |
| Maintenance | Sharpen or swap blades | Inspect lock, replace blades |
| Main risk | Slight point-of-impact shift | Mechanism failing to lock or open |
This is the short version. For the heads themselves, see the mechanical broadheads we tested.
Reliability Is the Core Difference
A fixed-blade head has no mechanism to fail. There is no O-ring, band or spring clip to wear out, and no blade that can open in the quiver or during carry. Our mechanical broadhead reviews note that the blade lock adds a point of failure that fixed blades do not have.
Cutting Diameter and Wound Channel
Mechanical heads such as the TenPoint Nemesis, with its staged 3.75-inch total cut, can make a larger wound channel than most fixed heads of similar weight. Their blades are folded in flight, so they add little drag. Fixed-blade heads usually top out around 1.5 to 2 inches of cut. You trade some cut size for blades that are in the same position on impact as they were on the rail.
Broadhead Flight With a Crossbow and Field-Point Match
A low-profile fixed head can fly almost like a field point. Exposed blades still add more drag than a mechanical head flying closed, so fixed blades are more sensitive to head alignment, bolt spec and consistent fletching. That is not a reason to avoid them. It is a reason to shoot your hunting head at your longest intended range before the season, as covered below.
Penetration Under Marginal Hits
Fixed blades have nothing to open, so they are commonly said to keep more energy for straight-line penetration. Hunters often report the difference most on a quartering shot that clips bone or passes through heavy muscle. That is one reason many hunters of larger or tougher game choose fixed blades.
Choosing Cutting Diameter and Blade Count
Matching Blade Count to Game Size
For deer-sized game, a two- or three-blade fixed head with a 1 to 1.5-inch cut works well when shot placement is accurate. For larger game where penetration matters more than cut width, such as elk, big hogs or bear where legal, a narrower two-blade head is generally the safer choice.
Many states set a minimum cutting width (commonly 3/4 or 7/8 inch, and 1 inch for elk in Pennsylvania); see crossbow hunting laws by state and confirm with your agency.
Cutting Diameter Isn't a Substitute for Shot Placement
A larger cut gives more margin for a slightly imperfect shot angle. It does not make up for poor shot selection. Treat cutting diameter as a safety margin for the imperfect shot, not a license to take questionable ones.
Kinetic Energy Still Matters
Fixed-blade broadheads do not lower your crossbow's kinetic energy needs. Commonly cited minimums run 25 to 41 foot-pounds of kinetic energy for deer-sized game, and larger species require meaningfully more. Our how fast does a crossbow bolt travel guide lists the speeds of the crossbows we cover, labelled as measured or rated, so you can check your crossbow delivers enough energy for your head and game. If you hunt larger, tougher game and want the most penetration margin, a high-kinetic-energy platform like our tested Ravin R29X or TenPoint TRX Ultra gives a two-blade fixed head more retained energy to work with on a marginal hit.
Sharpening and Maintenance
One-Piece Heads: Sharpen, Don't Replace
A one-piece fixed head is made to be resharpened with a broadhead sharpening tool or a fine-grit stone along the factory bevel. A well-kept one-piece head can last several seasons, so a good sharpening tool is worth buying if you plan to stay with this style.
Replaceable-Blade Heads: Swap, Don't Sharpen
Field-sharpening thin replaceable blades usually does more harm than good. The steel is often too thin to hold a hand-sharpened edge, and uneven sharpening can upset balance and flight. Carry a spare set and swap blades whenever they show dulling, nicks or bends.
Inspect Before Every Hunt
Whatever the design, check for bent blades, a loose ferrule-to-blade fit and corrosion on the edge before every hunt. A head that looked fine at the end of last season can pick up corrosion or edge damage over the off-season.
Storage Between Seasons
Store fixed-blade heads in a dry, temperature-stable case, not mounted on bolts in a garage or shed with big humidity swings. Surface corrosion on an edge can dull it, and a head packed away in December may need a fresh sharpening pass by August. A light coat of gun oil or a rust-preventative wipe before storage is a cheap habit that helps.
Practice Before You Hunt
Shoot the Actual Broadhead
Exposed blades add more drag than a mechanical head flying closed, so a fixed head's point of impact can shift further from your field points. Always shoot your actual hunting head at your expected distances before the season, and re-check zero whenever you change bolts, heads or scope settings.
Tuning Considerations
If your fixed head keeps grouping away from your field points, check head-to-shaft alignment first. Also consider the bolt's FOC, which our what is FOC guide explains. A head that is not true to the shaft will fly inconsistently whatever the blade design. Spinning the bolt by hand or on a spin tester can reveal wobble you cannot see at a glance.
When Broadhead-Specific Grouping Doesn't Improve
If alignment and vane clearance check out and your fixed-blade groups still open up, look at the bolt itself. Crossbow bolts are matched by length, weight and the manufacturer's approved list rather than spine charts; confirm your bolt meets your crossbow's spec before blaming the head. Our tested Wicked Ridge Match 400 and TenPoint CenterPunch HPX bolts are both good reference points for how insert weight and FOC affect this kind of broadhead-specific tuning.
Tested for this topic
Wicked Ridge Match 400 BoltA 46-grain insert and about 14% FOC; confirm the insert threading suits your broadhead.
Distance Matters More Than You'd Expect
A fixed head that matches field points at 20 yards can drift apart at 50 or 60 yards, because small aerodynamic differences grow with distance. If you plan to shoot at your longest practical range, check point of impact at that distance.
Which Head Suits Which Hunter
Match fixed blade crossbow broadheads to your situation, not to a brand claim.
- First broadhead, deer-sized game: a double-bevel, two- or three-blade head with replaceable blades is the forgiving starting point.
- You want to sharpen and keep heads for years: a one-piece head and a proper sharpening tool.
- You value blood-trail visibility in thick cover: a three- or four-blade head, perhaps with lighted bolts.
- Your crossbow is very fast: confirm the head's rated speed with the maker, then see which speeds our reviewed crossbows reach in how fast does a crossbow bolt travel.
- You prefer a larger cut: compare against the mechanical options in our broadhead roundup first.

Myths vs. Facts
| Common belief | What is actually true |
|---|---|
| A bigger cut always means a cleaner result | Cutting diameter adds margin for an imperfect shot, but shot placement and a head that flies true matter more |
| Fixed blades never need tuning | Exposed blades are more sensitive to alignment, vane clearance and bolt spec, so they usually need more checking, not less |
| A sharp head from the box is ready to hunt | Packaging, travel and storage can dull or corrode edges, so inspect it |
| More blades always means more damage | More blades widen the cut but raise resistance, so penetration can fall |
| Any fixed blade fits any bolt | Thread type, insert and total weight must match your bolt and crossbow manual |
| Field-point groups prove the head will group | Only the exact head you hunt with proves that, at your real distances |
Common Mistakes
- Choosing blade count by looks instead of the job. Pick for penetration or for a wider cut, not for appearance.
- Testing at 20 yards only. Small drift grows with distance, so test at your longest realistic shot.
- Hand-sharpening thin replaceable blades. Swap them instead, as described above.
- Leaving heads on bolts in a damp shed all winter. Store them dry and lightly protected.
- Skipping the spin check. A wobble you can see on the bench will show up downrange.
- Changing bolts after tuning. A new bolt changes weight and balance, so start the tuning check again.
A Step-by-Step Setup Check
Do this at the start of each season with the crossbow de-cocked while you handle the heads. Follow your crossbow and bolt manuals for torque and assembly specifics.
- Inspect each head for bent blades, nicks, corrosion and a loose blade or ferrule.
- Thread the head onto the bolt until it seats flush against the insert, with no gap.
- Spin the bolt on a flat surface or a spin tester and watch for wobble at the tip.
- Check vane clearance against your rail and rest once the head is on.
- Shoot field points to confirm your zero, then shoot the head at your intended distances.
- Compare groups. If the head lands away from the field points, adjust your sight to the head you will hunt with, then re-confirm.
- Retire any head that took a hard hit or shows damage you cannot correct.
Choosing by Priority: A Decision Table
| Your top priority | Lean toward | Watch for |
|---|---|---|
| Fewest things that can fail | Fixed blade, any design | Needs more tuning checks |
| Deepest straight-line penetration | Two-blade double-bevel | Narrower cut |
| Easier blood trail in cover | Three or four blades | Slightly more resistance |
| Years of reuse | One-piece head | Needs a sharpening tool and skill |
| Fast field swaps | Replaceable blades | Do not field-sharpen thin blades |
| Lowest set-up effort | Mechanical, flown closed | More parts to inspect, speed rating to confirm |
The right fixed head also depends on your bolts, so read our how to choose crossbow bolts guide, and use crossbow hunting laws by state to see where to look up local rules. Our best crossbows for deer hunting guide covers the crossbow side.

Frequently Asked Questions
Are fixed-blade broadheads better than mechanical broadheads?
Neither is universally better. Fixed blades have no moving parts to fail. Mechanical heads usually give a larger cut and flight closer to field points. Choose by whether reliability or cut size matters more for your hunting.
What cutting diameter should I choose for deer hunting?
A 1 to 1.5-inch cut on a two- or three-blade fixed head works for deer-sized game with accurate shot placement and enough kinetic energy. Check your state's minimum cutting width too; many set 3/4 or 7/8 inch.
Can I resharpen the blades?
One-piece fixed-blade heads are designed to be resharpened with a dedicated tool or fine-grit stone. Replaceable-blade heads should have their blade sets swapped rather than sharpened, since the thinner steel doesn't hold a field-sharpened edge reliably.
Do fixed-blade broadheads fly differently than field points?
They can, more so than a well-designed mechanical head flying closed, because exposed blades create more aerodynamic drag. Always shoot your actual hunting broadhead at your expected hunting distances before the season to confirm point of impact.
Are single-bevel fixed blades worth using on a crossbow?
Single-bevel heads can improve tissue separation on larger, tougher game, but they need more careful alignment and bolt matching than a double-bevel design. They're a reasonable upgrade once you're comfortable with fixed-blade fundamentals, not a recommended starting point.
How many practice shots should I take with a new head?
Shoot enough groups to see a consistent pattern at your real hunting distances, and compare them with your field points. If groups differ, check alignment and bolt spec before blaming the head, and re-check after any change of bolt or scope setting.
Why does my fixed-blade broadhead land away from my field points?
Exposed blades act like small wings, so misalignment, an unseated head or a bent shaft can steer the bolt. Check seating, spin the bolt for wobble, then confirm vane clearance and that the bolt meets your crossbow's spec before changing anything else.
Do I need to tune my crossbow for them?
Often a little checking is needed. Verify alignment, vane clearance and point of impact with the exact head, and follow your crossbow manual. If groups stay open, review the bolt's weight, length and balance against the manual.
How should I store them between seasons?
Keep them in a dry, temperature-stable case, not mounted on bolts in a damp garage. A light rust-preventative wipe on the blades is a cheap habit, and heads should be inspected again before the next season.
Is a fixed-blade broadhead legal everywhere?
Not necessarily. Some jurisdictions restrict head types, cutting diameters or hunting devices, so check current rules with your wildlife agency before you hunt. This guide is not legal advice.
Final Recommendation
Fixed-blade broadheads are the simplest, most failure-resistant choice for crossbow hunters. You trade some cut size and a little field-point drift for a head that has nothing to deploy. If you hunt larger or tougher game, want penetration on marginal angles, or simply want no moving parts, a quality fixed head is a sound choice.
