Bosch OSL138K 1-1/4 In. Starlock® Oscillating Multi Tool Hook Knife Blade

Perfect tool for breaking down lots of cardboard. So far I've used it to break down heavy duty shipping boxes for a couple of days and it is as sharp as ever. Fits perfectly with my little Bosch 12V oscillating tool.

I needed to cut a thick rubber mat and this was the exact tool I needed for the job. I didn’t want to hack at it with a utility knife, so this came in clutch

Useful blade for scraping caulk and other items off of flat surfaces

5 stars for performance. 4 stars for price/value. These blades are good, but should last a bit longer. We use this blade for removal of dried hard but brittle tile adhesive. Stardock is a superior system. Bosch and Anazon should have a accessory Sale every now and then.

This blade works wonderfully cutting shingles, cardboard and everything else that has been put against it. It is sharp, keep away from things you don't cut. Easy removal, cost effective, smooth use, and much more comfortable for long applications compared to utility knife holders.

I needed to recut a roof/wall intersection in some old architectural shingles. Two roof/wall transitions, I did the first one with a simple saw blade in the oscillating tool. It took a while and I worried a little that I would cut the step flashing (though it's galvanized). All of the teeth were worn off on the first shingle and cutting 10' of valley took 1/2" off length of the blade. That wall took an hour or so. So, I bought this blade for the other side. Wow, 10x as fast. Slices right through the shingles, asphalt, fiberglass and sand. I did pretty good at lifting just as I came to the bottom of each step (cutting up - trust me) but when I did catch a step, this blade would not cut it at all. I'm confident that I did not damage the flashing in this little adventure. Got that side cut in 10 minutes. The blade appears to have not worn down at all. I also tried this blade on some cardboard since it says it's for 'soft materials'. Cuts cardboard like buttah. I will say though - you want to know where your fingers are when using this particular blade.

This works when you have a long, straight, wide caulk bead to remove. If the caulk bead varies in thickness, as in the bathroom I just completed that had caulk inside irregular grout cracks, you may not be able to fit this tool into the crack. If you do have that long, straight, wide caulk bead, this will work well. It can be mounted onto any brand of oscillating tool with no problems. Be patient and go slow. Keep the flat side firmly against the edge of the caulk bead.

I recently saw a YouTube video that demonstrated the use of this blade for cutting cardboard; and I was amazed. I searched it out here on Amazon, and found this one for my star lock connected Bosch multitool. I couldn’t be happier. Overall a very useful blade that I’m glad to own.

Works very well for removing old silicone and caulking without damaging surrounding surfaces. The Starlock connection feels solid and does not slip during use. Used it on bathroom caulk and around windows with a multitool and it saved a lot of time compared to scraping by hand. Blade stayed sharp longer than expected. A bit expensive for a single blade, but the quality is much better than cheaper generic ones.

Good

Très satisfait

Would like it to be a tad more flexible but otherwise good

Quality Bosch blade for the starlock fit. Handy accessory blade to have when you need it.
