Review on Versatile EONLION 20 Multi-tool Blades: Perfect Fit for Fein, Porter Cable, Dewalt, Bosch, and More! by David Batte

So far the knives are on par with the Bosch and Dewalt brand knives I've used for years and cost a lot less. I generally feel you get what you pay for good value for money. These blades performed just as well as much more expensive brands. I'll note a small caveat: Blades marked for use with metal are used once for each application. I used them to cut off four small stainless steel screws and the teeth were gone. I think brands do the same. They may be ok with aluminum or soft metal.
