Until recently, I never liked the Small 21. On the other hand, the Large Insingo Micarta was my grail! Like someone said above, it just feels *right* in the hand. Finally getting one was a weird emotional experience. (Yeah, bizarre, I know!). But, for whatever reason (perhaps largely FOR thar reason) it mostly stays in the safe.
I picked up a Small 21 Micarta Tanto recently, primarily on impulse. I've always thought the Reeve Tanto looked pretty awesome and wanted to give it a try.
Well, I have not been able to put the Small 21 down since I got it! It has become my #1 EDC and possibly my favorite knife.
I think it is the perfect size for my "carry lots/use little" form of EDC. (I have a PM2 or SOG for when those roles are reversed.) It also satisfies my embarrassing need for "pocket jewelry."
Because I get the most joy out of it, I think I like the Small 21 best. But I never would have reached that conclusion without first being lucky enough to try the Umnumzaan, Large 21, and Small Inkosi (none of which are going anywhere soon, BTW). [emoji6]
Remember, I never used to like the Small 21.[emoji16]
Edit to add: With additional thought, if I were to loose both, the Large would sting more (grail knife) but the Small is the one I'd most likely replace.
