My wife's pretty sure you can have too many knives - at least she always says I do!
Last year I was in love with the Havalon Piranta because of its extremely low weight compared to other replaceable-blade options. But they're admittedly fragile knives (blades are easy to snap) and the blades are hard to replace. While I was out hunting, I found and brought home an antler from a spike bull, and my wife surprised me for my birthday this year by sending it away to a custom knife maker (Griska Knives). Here's what he made, I was obviously blown away:
Here's his Instagram if you want to see other knives he's done:
The two above are in different steels. The larger one has a thick spine and is D2 tool steel, while the smaller is a pukka-style with a spring-steel blade. Both are razor sharp and have fitted leather sheaths. They're so beautiful I barely want to use them - I can't stop looking at them.
That said, I also still have a "thing" for replaceable-blade options (and a knife addiction) so I recently picked up a Havalon Talon. I feel like it's a good compromise: it's replaceable, but with thicker blades and a stouter, fixed handle and the blades are much easier to replace. That's what's in my kill kit now. It's not perfect - in particular Havalon REALLY needs to get its act together on blade storage and disposal (Gerber nails this one IMO). But I like it.
