KISSWILL 10 Pack Mix Shape 45mm Rotary Cutting Blades - Fits OLFA, Fiskars, Martelli, Truecut 45mm Replacement Blades, Sharp and Durable

Right up front let me mention I am impressed with the speedy delivery. Item arrived more than a week AHEAD of the EARLIEST anticipated delivery date. Nice! I've done some quick tests with the regular cutters (wonderfully sharp!), small-tooth perf wheel, wide-tooth/wider-space perf wheel and the wiggly pinking cutter. They all work and will come in handy. As I expected, in my Fiskars rotary cutter handle, the thickness of the wiggly cutter edge will require a thin spacer behind it to shim it away from the handle. Should not be a big deal to make.I like the tidy little package the blades come in. It's got spindle they all stack on. (Some people may prefer having individual blades packed in individual safety covers so they can do an installation without risking touching the very sharp cutting edge. This is not that style of storage package.) The steel used, the fit and finish look to be excellent. There is a nicely viscous oily film on all the blades to protect from rust. It's easy to wipe off the blade when you decide to install it.I've never used either of the two perf blades or the wiggly pinking blade before. I do use pinking shears for various projects on both fabric and paper, so I look forward to the quick convenience of using a rotary cutter with the pinking pattern. The small-tooth/small-space perf wheel makes the kind of perforations in paper that allow you to tear it later. The perf wheel with wide teeth and bigger space between makes a series of small slots for a different purpose (not tearing). I've read about using those holes for stitching thick'ish fabrics together by weaving a cord or yarn through the perf holes. It might also be handy for "scoring" thick paper for easy folding.Using a new straight blade was fun. I didn't think my old Fiskars blade was dull, but my biceps are not going to get the same workout with the new super-sharp hot-knife-thru-butter blade in there. That will certainly improve cutting accuracy. At this low price (about $1/blade) I'll probably pop a new one in every time I begin a new project.My only overall criticism is that the hole in the center of each blade is a tiny bit larger than the hole in my Fiskars blade, which was a perfect fit on the Fiskars handle. Hence, the Kisswill blades have a tiny bit of play when mounted in the handle. (Also, while the Fiskars fits perfectly on the spindle of the Kisswill case, all the Kisswill blades have a tiny bit of play on that spindle.) It's not much (not like having loose lug bolts.... ha!) and I don't think it will affect cutting accuracy during use. If it does, I'll update this review.So far, I'm happy I got these. Good quality at the very reasonable price. And the cutting part of my life will be a snip easier!UPDATE!!! -- I've had a chance to use these now. They are all sharp and do cut well. One problem I noticed is that the hole in all of these is a bit larger than the Fiskars blade and the axle in the Fiskars handle. That makes these blades a little bit sloppy on the axle, but it's not a functional problem. A bigger deal is that the straight cutting blade and the big-space perf blade each have three notches in the hole that are each as big as the portion that rides on the axle. In use, you feel and hear a clickety "kla-dunk, kla-dunk, kls-dunk" as you are cutting. It's not a deal breaker. I'd still consider these blades worth using and a good deal, so worth buying. But it's a tiny bit irritating and will put some focused wear on the axle bolt. If I start to see a groove develop, I'll do another update.

These are as good as name brands and not as expensive. I really only needed straight and pinking blades, but these came with a couple of others as well. Be careful when handling - they are sharp! At this price, I won't be trying to get "extra" use out of my blades!

The plain blades worked great; nice and sharp. When I tried out the serated blades I was sorely disappointed. The ones with the cut-outs didn't cut AT ALL and the fluted one didn't allow for the guard to be slid into place. Anyway, the plain blades are fine.

I bought these blades as replacements for my Fiskar rotary cutter and they work great. They are nice and sharp and well worth the price.

I'm very pleased with the blades, very and a very low price.

I've now bled for my art, lol. They are very sharp and in getting them out of the case they came in cut myself. They come in a plastic case, covered in oil. They fit my handle great. I didn't especially want or need some of them, but then played around with them and think they might be useful down the road.

They don't stay super sharp for long and have some kind of clunky rotation, like the center hole has too much play. I have an old roller. I will prob buy again cuz they were cheap enough and stay sharp long enough for one project. But there is a reason olda are expensive. They are thick and sturdier and last hecka long

Good products.
