SchradeDelta Class Inert 7.5in with 3.25in AUS-8 Steel Blade and Aluminum Handle for EDC, Blue

I am a fan of the metal handle, the liner lock and the shape of the blade. it has a smooth action. Part of the reason for buying it is the unique style as well as the model name. I bought a different brand knife that had the name Exert, so Inert seemed like a fitting choice. Happy with my decision to purchase this knife. Using it lightly and cleaning the blade is easy. I wipe it off after using soap and water then let it air dry.

Confessions of a knife addict- I really like this Inert. I opened the package and inspected the knife slightly off center but clear of the liner. Blade is paper sharp but not phone book sharp but sharp. Scale patterns helps keep a secure grip. Some aluminum scales can be downright dangerous as the are slippery in light use. For 22 bucks very impressive. I would recommend. My collection is around 400 knives from some $8 Rough Ryders to Civivi, Kizer, Spyderco, Cold Steel, Chris Reeves, Microtech, Pro-Tech, ZT, Benchmade, Boker and many others. I’ve carried this Inert for a week straight very useful would not recommend for heavy use it’s a liner lock and aluminum gets slippery with sweat and other fluids.

At this price point, not bad at all. Solid construction, but at this size it could compete with some hot sellers with one overall change:Thin down everything, just a bit!Slimmer scales = weight reduction; slimmer/drilled liners = same effect. Cherry on top, take down 1/16" off the blade stock and grind it full flat, I don't see why this knife wouldn't be able to compete with a heavy hitter such as the Civivi Elementum. Steel selection is decent, action is good, and so are the ergos and profile aesthetics, combined with a great price could make this knife a rep healer for Schrade.

Great edc work knife, the deep carry clip is awesome. Sharp as always with schrade wish the inert came is a higher grade than Aus-8, maybe m390 would be great. But in all another excellent model by schrade.

I want to like this knife, but I just can't get past how bad the jimping is on the blade. It has way too sharp of edges and they should have been smoothed out. If this was meant to be more of a gentleman's knife it fails.The knife is well made other than that, and after a few strokes on a leather strop, the knife was very sharp.This is not a knife I would carry for everyday use because of how painful the jimping is to use, instead, it will be thrown in an extra BOB as a backup pocket knife.

Interesting style. I mainly use for opening letters and packages. Perfect for that, as the blade shape is kind of like a letter opener. Has good feel in the hand. Not the lightest but not heavy either. Only minor quip is the thumb scales on the top of the blade could be softened on the edges a little. The action is very nice and smooth, flips open completely even though it is not spring assisted. A slight pressure on the finger tip is all that is needed flip open, however it will not open accidentally. The blade release was stiff at first, but after some use it is no longer difficult. I've had a few months now, and not had to sharpen yet.

Love the blade shape, edge retention and smooth action. Much better than expected at this price point.

First of all, this thing does look attractive. I like the blade shape and the aluminum scales are very nice as well. The satin finish on the blade looks great, and the AUS-10 steel seems pretty solid so far. The action is pretty smooth after some lube and some breaking in. While it does have a bit of side-to-side play when open, it doesn’t have up-down lock rock, which is more important to me.But that’s about all I like.Starting simple: the pocket clip. Big round-top screws underneath a loop-over “deep carry” clip is a recipe for trouble. It makes it hard to seat the knife all the way down on my pocket seam, as the fabric gets hung up on the screws. Over time this also means it will tear the fabric up. Not cool, Schrade. You need to use countersunk screws, or don’t use this style of clip. Literally every guy with a YouTube channel doing knife reviews complains about this and most good knife companies these days (the ones who actually listen to customer feedback anyway) have stopped doing it, so there’s really no excuse for new designs to be coming out with this issue. Everyone hates it. Please stop doing it, guys!The jimping: the finishing on the grooves on the blade spine and the flipper tab is terrible, and really seems designed to punish the user for using the knife. The edges are sharp, hard, and brutal on your fingers. Ditto for the lockbar, it becomes painful to operate after a few times opening and closing it. You could actually cut yourself on the jimping if you aren’t careful handling the knife. I am not joking. It’s unpleasant to say the least. Probably great if you’re wearing gloves, though, as the roughness really adds a ton of traction…The blade: it’s pretty thick for an EDC knife, and with such a narrow blade there is no room for the grind to get down to a nice thin edge. So it’s very thick behind the edge and consequently doesn’t cut very well. It may be intended for tougher cutting tasks, I dunno, but the build quality doesn’t really allow for that; so I would much prefer a more slicey geometry that is thinner behind the edge than this is. Also I’ll add that the edge it came with out of the box was pretty dull and needed significant sharpening. It came at something closer to 23-25° per side, and I’d recommend lowering the edge bevel to 20° per side—or even 17° considering how thick the blade is.The pivot: I wanted to adjust the tightness of the pivot screw, but found that it had a lot of thread locker on it; and what’s worse, the pivot was free spinning. So you need to use a T8 bit driver on both sides of the pivot to do any adjusting…and that’s after you heat it up with a soldering iron to break the thread locker. Otherwise, if you only turn the screw on one side, the whole pivot just spins and you get nowhere. This is another thing that most knife companies these days have stopped doing, by using a D-shaped pivot that is captured so it can’t spin.The detent lash and/or pivot lash: If you don’t know what this is, it means that the blade has unnecessary play in it when seated inside the handle. When it’s closed, you can wiggle the blade to a significant degree; the blade will not fall out on its own, but it just has some movement when closed. If the detent ball pocket is properly milled and/or the hole that the pivot goes through in the tang is properly drilled out, there shouldn’t be any play. But this blade is pretty loose and gives you a feeling of it being really junky, as you can feel it shift and shake when holding in your hand and when touching the flipper tab. Now, it doesn’t affect the knife at all when it’s open and being used, but it’s one of those signs of quality that is important to look for.I really wanted to like this knife, but there are just too many unnecessary misses. For what I paid for it, I’m not too mad. But since Schrade seems to be trying to revamp their product line and get their name back on the map, I feel like they need to hear this kind of criticism so that they can see where they need to improve.
