I rotate knives once a while. Sell of the old ones, then get into the catalogues and buy some new ones.
In the last 2 years I bought 3 bark river knives, drop point Hunter, Scandi and Northstar. A friend made 2 Puukkos for me with Helle blades, one stacked birch bark, another burled birch with moose bone. Next gunshow I am going to sell my cleaver/caper combo knives of Alaska and their alpha wolf as well as my spyderco wegner model and the Bear cutlery folding Damascus with bone handle. Have done a couple of deer with all of my knives, except the bark River Scandi ready to do a whitetail for next year . I am still lusting for a Puukko made by a master like Malanika.
For EDC here in Edmonton we are restricted to the 3 inch blade length, I carry a small light 3 blade schrade with lots of patina. Good enough for strings, box opening, opening envelopes, cutting food items etc. I have tried much nicer EDC knives but found I disliked heavy knives in my pocket.
Sometimes I find if I am lusting after a certain knife and I wait another 2-3 weeks, often the feeling goes away.
Gues in the field of psychiatry they would classify us as Serial knife buyers. Wonder what theywould offer as therapy?
