A 4.72-inch folding knife with a two-inch blade is a statement about who it is for. Kizer's Walnut is an office knife, designed by in-house designer Mr. J as something you can open at a desk without clearing the room.
The numbers are unusual enough to be worth listing: 4.72 inches overall, a 1.97-inch sheepsfoot in N690 at 0.11 inch stock, a 2.7-inch G10 handle, 3.03 ounces, thumb-hole opening, tip-up clip. Kizer's copy frames the knife around a Tai Chi concept, which is marketing, but the geometry behind it is not: a short sheepsfoot with a low point is the safest blade shape to use near fingers and the least alarming to open in a meeting.
N690 is the choice that makes the knife worth $41.30. It is a cobalt-alloyed European stainless in the VG-10 family, with better corrosion resistance than 154CM and edge retention somewhere between 154CM and VG-10. On a two-inch blade it will hold a working edge through months of tape and envelopes. The trade is that a knife this small with a handle this short is a three-finger grip at best, and the 3.03-ounce weight is heavy for its footprint because the liners are steel.
Compared with Kizer's larger budget folders, the Walnut costs more per inch of blade than almost anything else in the catalog. The Sidekick at $26.40 gives you nearly an inch more blade for $15 less. What the Walnut buys is discretion, a blade that will not spook a coworker, and a steel that outlasts the 9Cr18MoV tier. That is a real use case, not a niche one.
Verdict: an office and travel knife with a sensible steel and a shape that will not get you a talking-to from HR. At $41.30 it is priced for the person who wants exactly one small folder, not the person collecting them.
