Seems like a Kiridashi might be a useful and easy carry. I'm intrigued, but the last thing I need is another blade sitting on the shelf. If you do think they are useful, what considerations should I take when choosing? I'm thinking the sheath or kydex could be important, or having a hole for a lanyard, or whether the blade is longer and pointy or stubby. I guess the steel is critical for such a small cutting surface. I have no clue, but they look kind of cool.
