I only have three, I keep looking but can't decide and also, at the moment, can't justify another, waiting for a momentous occasion...like finally doing a scuba course so I can justify a #16...a couple of times in the last couple of decades I went trough all my knives and if they were not getting used I did not keep them.

Down to a half dozen, #10-3 edc, #10-7 for carving roasts, #18-5.5 tramping/hunting, a big Nepalese khukuri, basically it gets used like an axe or a machete, a 'Woodlore' style blade that I handled myself because I wanted to see what all the fuss with a scandi blade was all about, and a Hinderer designed zero tolerance flipper, mainly I wanted to try a flipper.

All get use, I imaging if I had the space or spare income I could get into collecting stuff, not sure if it would be knives or something else, I'm not sure I have the right personality for collecting, if I have something I tend to have it because I want to use it.
Different horses for courses I guess!
