Universell passendes OPEN-LOK Diamond MAX Diamantkorn-Fugenentfernungs-Multifunktionswerkzeugblatt (1er-Pack)

Switched to this after burning through cheap blades, and the diamond grit on this one barely shows wear after a full bathroom re-grout. Cuts through old mortar clean without loading up or slowing down.

Finally a grout blade that actually lasts through an entire bathroom without wearing down. The grit on this one feels noticeably more aggressive than the cheapies, and it's cut through old mortar like butter.

I’ve been through three other blades on this same tile job, but this one cut through the old grout like butter and still looks brand new after a full bathroom floor. The diamond grit really holds up way longer than the standard carbide ones I used before.

Finally a grout blade that doesn't quit halfway through the job — even on the hardest old grout. The diamond grit held up noticeably better than the carbide ones I've tried before. It cut cleanly without much dust, which was a nice bonus.

Bought this for a kitchen backsplash demo and it chewed through old thinset like butter. The diamond grit edge is still sharp after an entire afternoon of cutting.

I’ve been using this on a bathroom reno and the diamond grit held up way longer than I expected—still sharp after a full day of grout removal. It cuts cleanly without excessive dust, which was a nice surprise.

This blade cut through old thinset like a hot knife through butter, and it still looks new after three full bathroom joints. The diamond grit really does hold up way better than the standard carbide ones I used before.

After struggling with worn-out carbide blades on a recent bathroom reno, this diamond grit blade cut through three different shower floor grout lines without a hint of slowdown. The 15x longer life claim feels legit with how aggressive it still cuts.

I had to replace a cheap carbide blade halfway through a bathroom job, but this one cut through the old grout lines without slowing down. It's noticeably quieter than what I've used before, which was a nice surprise.

The diamond grit held up perfectly through a full shower regrout job without any noticeable wear. It cuts fast and clean, but you do have to be careful not to push too hard or it can grab.
