KB Knives Relentless Button Lock Gray Folding Knife [KB462A]

Relentless — a tanto blade with external button release

The Relentless pairs an angular tanto cutting profile with a button-controlled folding mechanism. The button provides the stated release interface; it does not by itself establish automatic opening or replace the blade’s separate opening purchase.

Opening and lock operation

The external button releases the blade lock for closing. The button is a lock control; the opening method remains the one shown for this model, rather than being defined by the word “button.”

Steel and maintenance

M390 is a powder-metallurgy stainless steel with high wear resistance and good corrosion resistance. Its appeal is an edge that resists abrasive wear during repeated cutting; regular light maintenance helps avoid a more demanding full resharpening.

Handle construction

Titanium provides a corrosion-resistant metal structure. Anodizing and surface machining change its appearance and contact texture; they are different treatments from adding a separate grip scale or inlay.
