waki. it's so unique. plenty of bowies out there to replace the mistress on the cheap, but not the waki.

also, practicality is a terrible reason to buy infi. also doubt it's your first knife or you "need" either, so get the one that's harder to substitute for.

finally, the BWBM just went on sale, will be for a good period, then will disappear and be available later at the company store. you have plenty of time to change your mind, sell the waki, and use the proceeds on your mistress if it must only be one.
