I recently recently sold my collection of about 35 knives from Cold Steel, Benchmade, ESEE etc. And restarted now I don't have much of a collection but I have a knife everywhere I need one. I have 4 busses, a victorinox tinker, ZT 560, Leatherman super tool 300, gransfors bruks hunters axe and a mora.
So 9 blades for me. I plan to upgrade the the 560 to a xm18 and get a RMJ shrike, an OTF auto and a couple more busses and hinderers. I feel pretty confident in saying my collection will not get above 25
