Norske Tools NOTP233 Multi-Material Oscillating Multi Tool Accessory Blade for Ashphalt Shingles, Thin PVC Floors, Carpet & Padding, Roofing Fabric and Foam Insulation

i needed to remove a lot of thick failing caulk around windows. the blade seems to be of a soft steel and wears quickly, but it was able to help me remove a lot of caulk quickly. it works better as a scraper than a saw regardless of the serrations. I was able to place it against the siding and separate the caulk from the siding fairly quickly. at $7.50 it was a good deal for what it is. I wouldn't pay much over $10 for it though as it wears too quickly. One thing to keep in mind, the blue paint comes off on everything and you will want to make sure anything you use it against will be painted.

First off, this is not meant for cutting nails, so disregard those negative reviews. This is for scraping soft materials off of a surface. Used it to remove silicone behind window panes without breaking the windows. Also used it to take up cupped linoleum around corners so I could lay plank flooring. Understand what this tool is for and it will serve you well.

Ever time I have to recaulk a tub or shower I try a different method and everytime I end up just going back to using my putty knife and utility knife. Maybe this has a use case but it wasn't my shower.

It took a fair amount of work but I was able to cut through old caulking between the base of my toilet and the floor. I don’t know how else I would have done it. A spray softener did not do the trick for this application

Might be my tool but I get a lot more vibration to tool with this blade. Seems sharp and pretty convenient if hard to reach spot is further than normal.

Used this while renovating a bedroom. I was able to neatly separate heavily painted baseboard molding from sheetrock without destroying either.

Just bought these and tested them out by cutting through some solid oak stair banisters... cut through them like butter. 10x better than the other Dewalt ones I had been using before. I'll only be keeping these in my toolbox from now on. I can't speak to their longevity yet, but given how fast and cleanly they cut it's not even a factor. The only thing is they will leave some slightly blue smudges on the material being cut if it's a deep cut and they get too hot, but for 99% of tasks this is not an issue.

the paint on the blade will come off on you cleanup project.
