Update - I bought a used Benchmade Bugout Mini and am awaiting the UKPK as well.
I like the look of that Doug Ritter RSK, but they copied the Axis Lock, which to me is pretty lame. If I'm going to pay big bucks for an Axis Lock knife, I'd rather give the money to Benchmade.
I have a Native, blade's a bit short. Para 3 is bulkier/heavier than what I like. The others are way out of budget.
A little too short for my needs, this time.
I've got about 50 SAKs, so you're preaching to the choir. I think my favorite is the Super Tinker or the custom Compact with the inline Phillips and magnifier layer added.
I go for years at a time carrying only a SAK, (and having them stashed everywhere) but I always come back to adding a folder too, because the SAK mfrs. refuse to use a blade steel with decent hardness. (Rc > 57) God forbid they have to handle more than one type of steel; it would just wreck everything. :-\ SAKs are easy to sharpen, but I just don't WANT to sharpen them every week. I do have a Leatherman Charge Al that rides in my usual shoulder bag; it has a 154CM plain blade that is just great, as well as two bit drivers, scissors, etc.
SAK makes premium priced blades just not premium performance.
Got a Delica, forgot about the Sage. Going to have a look at it and add either it or a Chaparral to my Wish List for the future.
