Customer Rating: - Greatest Invention Since Sliced Bread
While the blades are expensive relative to other types of blades on the market, the Fein Multimaster and the blades offered allow for tasks that other tools simply cannot do. I recently had an old roof decking board (slats, not plywood) warp causing a big hump on my roof. As it turned out, this was from water getting in from a bad repair before. With the Fein and the E-cut blades, I was able to cut out the warped section of board from inside the attic and replace it with a new section of board without cutting into adjacent boards and without damaging the shingles. This kept me from having to remove and replace shingles and roofing felt unnecessarily. I also used the scraper blade to remove huge amounts of caulk along the edges of a shower/tub unit that looked like someone just slapped the stuff onto the surface. The profile sanding kit made really quick work of a contoured edge of some night tables. It would have taken at least an hour of non-stop hand sanding to do the two tables. With the Fein, it took about two minutes per table, if that. People have been amazed at how good the tables look given how bad they looked before with the old, ratty paint they had and it's not like I had experience. These were my first furniture pieces that I refinished. Yes, the Fein Multimaster and accessories are not cheap but they will save you a lot of time and a lot of cussing which make them priceless to me.

Customer Rating: - Fein replacement blades
Great product, way too expensive. Would use tool more if the replacement blade wern't so expensive.

Customer Rating: - Better than I thought
After purchasing the Multimaster kit with multiple accessories, I was a little reluctant to use the E-cut blade for anything but wood. After a short time of usage, it was clear that I would need to cut through some nail embedded wood. I was shocked to see that blade was still sharp as new. I was sold immediately. I purchased additional blades only after I unknowingly cut through a couple drywall screws in a counter top. The blades' teeth wore down from being razor-sharp to an almost toothless state. Believe it or not, I still use the blade when I'm not sure what is embedded in the wood and it still cuts! My suggestion for long life would be to avoid any hardened metal such as drywall screws, cut nails , etc and you'll be happy with these blades.

If you do not have a Fein multi master, get on line and order one. This is an awesome tool and blows away the others. Especially if you are a contractor, the similar tools are more a handy man around the house tool where the Fein is a contractor ready tool
