Busse Crab Trail Custom Shop — NorCal Upland Knife Review
Editor's Personal Pick — This is gear our editor carries afield.
Editor's pick: the INFI-steel fixed blade that out-thinks every other knife in your vest pocket.
Why we picked this
Busse Combat occupies a corner of the knife world that's hard to explain to people who haven't held one. They make knives in Wauseon, Ohio, from their proprietary INFI steel — a CPM-3V derivative with serious carbide structure that takes an edge, holds it, and refuses to chip even under abuse no sane person would inflict on a knife. The Crab Trail is their upland-friendly Custom Shop offering — a smaller, more pointed blade than their larger combat-shaped knives, designed for the precise work that bird hunting and small-game dressing requires.

The full review
The thing to understand about Busse knives — and the Crab Trail specifically — is that the steel is the entire story. INFI is genuinely different from premium production steels. It has the toughness of a 5160 carbon steel (impact-resistant, refuses to chip) with the corrosion resistance and edge retention of premium tool steels (S30V, M390). Most knife makers can't replicate INFI because it's proprietary; the result is a steel that does what no other production steel does.
In practical terms: the Crab Trail will dress fifty quail without sharpening. It will hold its edge through five hundred. The blade will not chip if you accidentally hit a vertebra during a deer dress (this is the use case INFI was originally engineered for — combat-knife durability that survives accidental abuse). For a $385 knife, the steel alone justifies the price; everything else is a bonus.
The Crab Trail's geometry is upland-friendly in a way that Busse's larger blades aren't. The blade is 4 inches — large enough to break down a bird in a single motion, small enough to carry in a vest pocket. The point is fine enough for precise cuts (skin around a wing joint, removing a tail) without being so fine it bends. The drop-point profile gives you belly for skinning and a point for piercing.
The handles are full-tang construction with either micarta or G10 scales (custom shop options vary by drop). The micarta develops a patina with use that some hunters love and some find off-putting; G10 stays the same forever. Either is correct.
The sheath is the area where you'll customize. Busse ships the Crab Trail with a kydex sheath that works but isn't optimized for vest carry. Aftermarket kydex makers like Azweilke (see the dedicated entry) build sheaths sized specifically for the Crab Trail and integrated with strap-vest MOLLE — worth the additional investment if you carry a strap vest.
The Custom Shop nature of Busse means availability is unpredictable. Drops happen periodically; sizes and handle materials vary. Get on Busse's email list, watch the BladeForums Busse subforum, and be ready to act when a Crab Trail you want comes available. Pre-owned Crab Trails on the secondary market routinely sell for above MSRP — these knives hold value.
What we love
- INFI steel — genuinely better than premium production steels for impact resistance.
- 4" blade size — perfect for upland work without being oversized.
- Full-tang construction — bombproof, no failure modes.
- Lifetime warranty — Busse replaces anything, no questions.
- Holds value — better than a savings account, in steel form.
What to know before you buy
- Custom Shop drops are unpredictable — get on the email list and watch BladeForums.
- The kydex sheath isn't optimal for vest carry — plan for an aftermarket sheath (see Azweilke).
- INFI sharpens slowly — the same toughness that makes it durable means resharpening takes longer. Use a high-quality stone.
- Heavier than a folder — 5 oz is real weight in a vest. Worth it for the durability.
- Pre-owned market is robust — if a new drop isn't available, BladeForums Buy/Sell is your friend.
Where to buy
- Buy direct from Busse Combat (brand-direct — primary source)
- BladeForums Busse Subforum (secondary market for past drops)
