Matt can you put the web address of the replacement blades for the fein i cannot find the link. Cheers Steve.
I just got some from this company but haven't used them yet. The reports I've heard are fairly positive though http://www.sharkblades.co.uk/
ive got the worx sonicrafter, and i use the blades off sharkblades, work fantastic for me, but dont no about the fein
I only use the ones from shark blades for my fein and work fine if anything I would say they last a bit longer than original ones even when you hit a nail, the only thing I have noticed is sometimes they have a tendency to bounce a bit if that makes sense but just need to use them bit slower
