Fixed-Blade vs. Mechanical Broadheads: What’s the Difference?

Same Job, Two Different Approaches

A broadhead’s job is simple: cut a wound channel large enough for a fast, ethical harvest. Fixed-blade and mechanical (expandable) broadheads both get there by different mechanical routes — the right one depends on your bow setup and what you’re hunting.

Fixed-Blade Broadheads

A fixed-blade broadhead’s cutting edges are locked at full width from the moment it leaves the bow. No moving parts to potentially fail on impact, generally deeper penetration, and better performance through heavier bone. The trade-off: fixed blades typically fly slightly less like field points, so practicing with your actual broadheads matters more.

Mechanical Broadheads

A mechanical broadhead flies closed, at a smaller diameter, and opens on impact — giving it a flight path nearly identical to field points. The trade-off is that opening the blades consumes some kinetic energy, and there’s a moving mechanism that has to function correctly on impact.

Which One Fits Your Setup

• Lower draw weight or draw length: fixed-blade broadheads generally penetrate more reliably with less energy to spend.
• Heavier game or heavy bone: fixed blades hold up better.
• Want field-point-identical flight with minimal extra tuning: mechanicals are more forgiving.

Check Your State’s Rules

Some states restrict mechanical broadheads or set minimum cutting-diameter requirements. Check your state wildlife agency’s regulations before you hunt.
