How thick should a hunting knife be?
Updated 2026-09-08
For skinning and field dressing, thinner is better — most dedicated hunting blades sit around 0.10 to 0.14 inches at the spine. Save the quarter-inch stock for bushcraft knives that get batoned through wood; on an animal that thickness just wedges the cut open instead of parting it.
Why thickness beats steel for cutting feel
People blame steel for a knife that cuts poorly when the culprit is almost always geometry. A thick blade has to push material apart as it goes; a thin one parts it. Two knives in identical steel with identical edges will feel completely different if one is 0.09 inches at the spine and the other is 0.25.
The ranges that make sense
Skinning and caping blades run thin. General hunting fixed blades sit in the middle. Bushcraft and survival knives run thick because they are expected to be hammered through wood, and a thin blade in that role snaps. Our catalog spans nearly three to one across these roles, and every knife's page shows its spine drawn at the same scale as its blade so the difference is visible rather than notional.
Grind changes the answer
Spine thickness is only half the story — a thick blade with a full flat or hollow grind can still be thin behind the edge, which is where cutting actually happens. That is why hollow-ground hunting knives slice so well despite respectable spine stock.
