Downsides? Quality of the blades, no doubt. Like simply carrying a utility knife? And, when in the field (on my farm), no place to store the used blade. I can't simply stick the used blade in my pocket.

Other than that, opinions?

I like them for hunting purposes like skinning but are too fragile for a camp/general purposes knife.

thnx

Love the Havalons with replaceable blades for skinning type things. For everyday use, like amc says, too fragile

I carry a Milwaukee fastback 1505 at work.
There is a compartment in the handle to carry a spare blade. You can swap the blades out in the field without having to worry about where to put the used blade.

Cold Steel makes something called a Click n Cut which is basically like a heavy duty utility knife with replaceable blades of difference shapes and uses.

Love my Havalon for hunting. One proviso though, you must learn to use it for slicing motions. If you have some sort of wrist English or start a prying motion the blade comes right off.

Hunting with a professional meat cutter demonstrated this superbly. He couldn’t get 5 minutes of use without disabling the knife. Mind you he’s cut more meat in a week than I will be able to do in a lifetime. But, I’ve skinned and quartered 3 elk and a deer and probably pop off one blade per animal. There are a couple other brands that might address the blade issues some find. I simply shove the used blades into the dirt. I imagine a kid finding it a thousand years from now wondering about it like a stone arrowhead.

For use on the daily I carry one of the Milwaukee Fastback utility folders. I’ve had 3 different models, for me the most compact hit the sweet spot. If I used it a bunch on abrasive material the one with the blade reservoir would get the nod. The all metal if I was wearing heavy gloves all the time and stored it in a tool belt.

I have a couple different ones , the Civivi , Milwaukee fast back and the Tyrant .
The Tyrant is my favorite.
Full Titanium frame lock , lockbar insert & running on bearings.
No tool to replace or switch blade around. Also has a prybar .
Available on Amazon for $85
