The Kumo is superb. The law in my area precludes carrying it, except perhaps in a sporting/hiking scenario, for which it is not designed.
Nevertheless, the Kumo is an excellent defensive piece, and the "static-line" carry espoused by Blades is efficient and effective. The spear point blade, combined with the relatively neutral handle shape makes it a great pikal blade. The resin-coated, cord-wrapped, quasi-Japanese handle is attractive and practical. It's "grabby" enough to most likely preclude hand slippage, but thumb-capping would be good idea anyway, to avoid self-injury while thrusting in reverse grip. At the end of the handle is a nice punyo , with lanyard hole. A lanyard, or fob, also facilitates the static-line draw.
