I have a FFBM that needs a tough sheath. I bought it off of fleaBay and it came with a nice but delicate leather sheath, useless for how I abuse my big knives. This is my first Busse and I am amazed that the hype about INFI is all true. Put me down for a foot long if the FFBM fits. The Scottish patch looks the best to me but I like them all.
