This review is for a set of blades sold as Amazon ASIN B0DVCHWYJQ by American Mutt Tools.These are advertised for soft metals, wood, and plastic. There are four sizes, three of which will cut relatively small radius paths, and one that only cuts broad curves. The blades come in individual recloseable bags, each with a clear label with the type of blade marked on it.I find it humorous that the saw is illustrated in the listing with a two-by-four stud. I would hate to have to slice through a two-by-four with a coping saw.The higher teeth counts might be good for finish work in one step, for those with the dexterity to do that. I do my cuts with the coarser blades, because I expect to finish them smooth later anyway.I think the set is a good assortment and thus a good value, listing for about USD$13 at the time of this review. It becomes an even better value if there is a coupon or discount applied.

I went to use my coping saw the other day only to find that the old blade was rusty and dull. Ruh roh! This set looked interesting - I’d never heard of Mutt Tools before, but I decided to give them a chance.I like that there are 4 blade sizes. I’ve only ever used tiny 16 TPI blades in my old coping saw, but as I do more and more projects (including dovetailing) the variety will be useful. The blades are thin, so use care because they will bend easily. When the blade is in the coping saw frame, though, it’s quite strong. It’s also SHARP. I was able to cut the slot by hand very quickly, the and the blade followed my eye line easily.I have a few projects planned over the next few months (Christmas presents) and I’m looking forward to trying the rest of these out on my air fryer basket hooks (no patent pending). Oh, and box dovetails. Wish me luck!

This is a good assortment of blades for the standard 6 1/2 inch coping saws that you get at the big box stores. I tried the thinnest ones on some veneered plywood and they did a nice job. The only fault I have with the set is that the finest toothed blade, the 28 tpi, is thick making it unsuitable for coping work. I don't know why they did that, the purpose of a coping saw is to make circular cuts.

I don’t have woodworking skills, and only occasionally use a coping saw for random things. This is a nice assortment of blades for me to try out, and all fit in my saw perfectly. The three coarser toothed blades are 0.120” (3/25”) deep, and the finest toothed one is double that, at about 6/25”, so is not meant for making curved cuts. All the blades worked well and did not break. I don’t have enough experience with different types of coping saw blades to know how much tear out is expected with these blades. If you can stand watching my terrible sawing skills in the video, I show some of that as I cut out irregular shapes that were supposed to be straight lines :-)These blades seem better than the ones that came with my cheap saw, and I’m happy to have these to use.Addendum: A reviewer mentioned that some blades seem thicker than others and hard to fit in their saw. I had no problem with my cheap Cobalt saw, but a better quality one with tighter tolerances may be different. I went back and measured the thickness of each blade, and the metal is all about 0.38mm thick. However, the teeth on the 28tpi blade go all the way to the end, and the teeth sticking out makes the end wider. The teeth on the others don’t go to the end. I also noticed that the blades are often bent a little bit past the pins, and that bend may make it difficult to get some blades installed. I’ve added four more photos, and in the one with the bent ends, I only used one of them for testing; the others are unused.

I have a small metal coping saw I use for jewelry and other things, but is only has a 3 inch depth and 4 1/2 inch blades. I have a couple of wood projects in mind where I would need to cut some details into a piece that is more than 5 inches from the edge and figured a coping saw would work. I saw this set of blades and ordered them.I didn't realize my metal set is only a clamp type and wouldn't accept these blades (with the locking pins) even though it can expand to hold longer blades. The metal blades will cut wood, but very slowly even though it's a soft wood, which is why I ordered this wood blade set. I just got another saw that accepts the pin type blades and tested it out.The blades lock in nicely and the pins help to get nice tension on the blades for cutting. Much easier to get the blade tight when set up than the clamp type. I did a test project on some scrap plywood I have and it went fairly well. The blades cut the wood fairly easily, but since I didn't have a cutting block setup it the video is a little rough. The teeth pulled some of the back side off and also splintered, but this plywood is thin and soft so I expected that might happen.On a hardwood dowel I tried it went much smoother, but forgot to get video or pics for that one.
