Overview & First Impressions
Raising a copper vessel is a hammering process: you sink a disc, you anneal it, you raise the wall in overlapping courses and you anneal again. Between heats you trim, you mark, you cut the rim and you pare the seam. The Bestech Kriya BT2606E, a frame-lock folder in M398 with a bead blasted DLC titanium handle, is the sort of knife a smith keeps beside the anvil rather than in a display case.
Materials & Construction
M398 is Bohler's high-vanadium powder steel, and the machine satin DLC finish on this blade is a sensible pairing because it lowers friction and hides the marks that metalwork leaves on a polished bevel. Edge retention is the reason to choose it: you can trim copper foil, cut abrasive paper and slice leather for a hammer wrap in one session and still shave with the edge afterwards. Bestech knives runs it hard.
Design & Details
The frame lock is machined into the titanium handle, and the ripple pattern on the bead blasted DLC finish gives the surface a texture that holds up to oily hands. The knife is a full-size folder with a stout pivot, which matters when you are cutting against a bench stake. The flipper is crisp and the blade detents positively, so it does not open in a pocket full of brass offcuts.
Real-World Use
On a metal bench this knife trims annealed sheet, cuts the tape on a bundle of copper blanks, slices abrasive cloth into strips, pares leather for a mallet wrap and opens boxes of rivets. Among EDC knives with decorative finishes, the Kriya survives a shop because the DLC coating resists the fine metal dust that gets into everything and wipes off with a rag rather than scratching into the surface.
Ownership Notes
Wipe the blade after cutting abrasive cloth, because aluminium oxide grit left in the pivot will lap the washers flat. Keep the DLC finish away from scouring pads, which will dull it to a grey haze. Oil the pivot sparingly, since a heavy film attracts metal dust, and store the knife closed in a drawer with a silica pack in a damp workshop. Most folding knives that reach a metal shop end up as scrapers within a month. This one survives because the DLC finish resists fine metal dust and the pivot stays tight, which is what a smith actually needs between one heat and the next.
Who Is This For?
Buy this if you raise, forge or finish metal and you want a knife that can take a fine edge and hold it through abrasive work. It also suits the collector who appreciates a high-vanadium steel in a titanium frame. Skip it if you need a cheap beater for a shared shop. EdcMall lists the Kriya in several handle variants.
Final Verdict
The BT2606E is a serious folder for people who work metal. M398 with a DLC coating, a ripple-textured titanium frame lock and a stout pivot add up to a knife that behaves like a bench tool and looks like a limited run. Buy it, keep the grit out of the pivot, and it will still be tight after a hundred heats.
