Outstanding pocket knife
This knife is great for everyday use. Easy to open and close and it is wonderfully sharp. It cuts through packaging and other items that need to be cut open with ease. Simply the perfect pocket knife.

Good, not great
Smaller than I expected. Considering that this is a smaller knife, it is stiff to deploy. Handle edges seem a little sharp. I wish they were more "rounded". Blade is plenty sharp. Light weight.I own about 20 knives similar to this one (size, $, functionality, comfort). I'd consider this one about average. CRKT Shenanigan leads the pack.

CRKT and the M21 A knife for all seasons
CRKT is one of my favorite manufacturers. I like the R&D focus on locking the blade properly...after all the one thing that makes a folder less stable, than a fixed blade, or a Butterfly knife, is the joint, hence making this joint as secure as possible seems like a worthy pursuit. To that end this company has produced a few types of innovations, such as a liner lock button on some models, a knife that comes out from a different direction, etc.Like so many of their other blades this knife speaks to me with its functional design, weight, balance, easy adjustable opening mechanism, and... the knife is delivered with a usable sharp blade. Pet peeve alert: I do not like to have to do a major sharpening job on a knife, unless I am buying a butter knife. The M21 like many CRKT knives I enjoy, looks modern & elegant, even the serrated blade section does not look cheap, as it does with so many knives,. This is a beautiful knife and for the price point it is truly an exceptional design. For example, the two flanks that allow one to open the blade can act as a guard, have jimping for fingers, and two holes so the blade can be used as a spear. To me the M21 encompasses everything I like about this company and knives it produces. The knife is a perfect size, locks up with no give, is durable and sharp.

An OK Knife for Random Home-tasks
This is a fine, little knife if you want something to carry at home and pick weeds, cut the occasional small rope, or get gunk out of a crevice. The steel in the blade does not keep a very good edge, so I would not rely on it for a survival situation, or as a tactical knife in a war zone. This is one you keep at home in the junk drawer, in the garden shed, or in your glove box. Mechanically, its a little awkward to open, requires more manipulation than I would like.I lost it at work a while ago, and later saw someone with it talking about how they found it in the parking lot. I didn't really care enough about it to ask for it back,

Heavens, this is a steal
This knife is so fantastic I bought several more for gifts and just to have when I eventually lose it. I got it to replace an M16 that I carried for over a decade and elves or whatever finally stole out of my pocket. I was on the fence about the double hilt, but it's got such an understated profile that it's not getting caught in and out of the pocket. Might be an issue if you wear fashion jeans, but there's not a huge union between the populations that do that and the one that carries a pocket knife. The balance feels wonderful and the length is perfect for EDC. Anything bigger than this and I think you're compensating for something. Love the stainless body and I'm really enjoying the belly on the blade. Less of an issue because these things can be adjusted, but out of the box the clip is just the right tightness and so are the open/close action and the frame lock. One handed operation from day one. Can't comment on how well it holds an edge yet, but for this price vs. feature mix I really couldn't care less. In fact, if it holds an edge longer than a couple of weeks I'm going to have anxiety about the price being so low.
