BM42 BM43 BM47 Sanding-finish Portable Folding Knife Outdoor

The BM42 BM43 BM47 Sanding-finish Portable Folding Knife is a butterfly-style folder built around a 440C stainless steel blade and a sandblasted cast-steel handle. Open, it measures 24cm overall with a 9.5cm blade, a 13.6cm handle and a slim 0.3cm blade thickness. The hollowed-out handle keeps weight down while keeping the classic swing-handle feel, and the sandblasted surface gives the metal a matte, non-reflective look. At 24cm open it still folds down small enough to slip into a jacket pocket or daypack, so it travels without getting in the way.

Choose from BM42, BM43 or BM47. All three share the same handle construction, the same 440C steel and the same overall dimensions, so the choice comes down to the named option you prefer. Each knife weighs 161g to 168g on its own and 220g to 226g with packaging, and ships with a black nylon sheath for storage.

Hardened to 59 to 60 HRC, the 440C blade holds a working edge through repeated cutting, while the drilled cast-steel handle adds visual texture without extra heft. Whether you collect, practice handling or just want a compact outdoor folder, this BM series gives you three distinct options in one listing, each ready to flip open when you need it.
