Fantastic

Bought one to get my hands on a shark lock without spending a bunch of money and because it uses standard blades. I’ve been using it almost every day for a couple of months now and it’s fantastic. Super lockup, easy blade change, small profile, durable. I thought initially it was a little spendy for a utility knife, but it’s been worth every dollar. I really love mine.

Very nice

I thought that the screw that holds the blade would back out without locktight but so far no such problem. This thing is awesome. I love the sharklock. Feels almost exactly the same as the AD20.5.

Not bad at all. Could use some Micarta scales.

I have been daily carrying this knife since I got it. I carry a utility knife every day. I use it to cut boxes, open packages, and do things with the blade that I wouldn't want to do with my pocket knife. The shark lock is one of my favorite features. I also do like the torx screw for blade changes. I have no problem at all with needing a tool for blade swaps. People who want a quick change mechanism just don't understand how bulky and low tolerance quick change systems are. The screw fastener uses the least space and secures the blade for precision cuts. The GRN scales are not for everyone. The texture is grippy enough. I think that many people will conclude that the knife feels cheap with these scales. G10 options, Ultem, or even Titanium variants would be welcome. Despite the knife being able to fold. It is chonky. It's much wider when closed than my Kiser Drop bear Uti, and both are thicker than my TiRant Razor V2. I have many folding EDC utility knives. The locking mechanism is very figety and fun to use. The deep carry pocket clip works great and the thumbstuds allow for easy operation. This Utility knife does need to be broken in. It has significant lock stick when it comes out of the package. Not terrible, but you will notice it right away and playing with it for a while corrects the issue easily.

Suggestion

Having a removable screw can become a problem. I have another knife that is useless because of screw issues. Seems to me it would not be a big deal to put the same size extra screws in the holes not used to secure the clip. In other words, use the same size screws for the blade and the clip, that way the screws that are not in use can be 2 replacement screws. Also, provide a way to purchase new screws, this is not an option for the pry bar that used to be a utility knife sitting on my bench.

The unique value of a Demko original utility blade knife.

The finish is beautiful, with excellent bead-blasted areas, well-executed clip work, and impressive assembly precision. Overall, it has a very high-quality feel. The opening action has a solid, satisfying click that immediately tells you, “This is a well-made piece.” The Zytel handle has a surface texture reminiscent of G10, giving it a stylish look and a positive impression. As a Demko fan, this was my first time experiencing the Shark-Lock, and paired with the utility blade system, it felt a bit unique. The “shark fin” requires a longer stroke and has more sliding surface than I expected, which means it takes a bit more effort to operate. One-handed use also requires shifting your grip, which feels slightly less convenient. The lock itself seems impressively strong, as expected, but in this configuration, the balance between lock strength and blade retention feels slightly mismatched. The short grip makes it harder to apply force, and even if you do, the blade retention seems to give way before the lock does—so the lock’s full potential isn’t fully realized. That said, this is understandable since the lock was originally designed for standard blades. Additionally, the spine support needed to extend the usable cutting length introduces a slight snag when withdrawing the blade after a cut. This isn’t unique to Demko—many knives with similar structures share this trait—but it’s something you notice in use. Still, Demko’s willingness to experiment with mechanisms and explore new directions remains exciting. As someone who still considers the Tri-Ad Lock the “ultimate practical solution,” trying out a new lock and utility blade concept was a fascinating experience. For urban environments, offices, or desktops—where pulling out a big custom knife would feel excessive—this Demko original offers plenty of value for everyday tasks. I usually use a Milwaukee Fastback Mini, and in pure convenience, that probably wins. But the Demko brings something extra: the “fun” factor. And honestly, isn’t that sense of fun an important part of what makes a tool great?

It's ok.

It's a razor knife with a shark lock. Mine has a sticky lock. I feel it's overpriced for what it is. If you like Demkos and the shark lock then you'll probably get it no matter my opinion. My opinion is there are better options.
