The Tigers Teeth Blades oscillating blade sharpener is quick and easy to use. It sells online for $179, and the adapter (available for all major tool brands) sells for $25.
Wood floor pro David Merrill, owner at Spring Grove, Ill.-based Totallywood Flooring, tried the Tigers Teeth Blades oscillating blade sharpener:
I think the oscillating tool is one of the greatest tools ever invented, and I use it constantly when installing wood flooring for everything from cutting in vents to undercutting door jambs (and much more). You can get cheap oscillating blades on Amazon, but I use the actual Fein blades, and they aren’t cheap—something like $8 per blade. When you’re using the oscillating tool a lot, especially when cutting thick hardwoods, the blades get hot, get dull and get annihilated pretty quickly.
Since I go through so many blades and was just throwing them in the trash when they got dull, I was really interested to try the Tigers Teeth Blades oscillating blade sharpener. The version I got is the sharpener with the CNB coating (cubic boron nitride) for steel blades (there’s another version with diamond for carbide blades). The sharpener runs on 20-volt batteries, and Tigers Teeth offers battery adapters for all the major tool manufacturers: Bosch, DeWalt, Kobalt, Makita, Milwaukee, Ridgid and Ryobi.
It’s extremely fast and easy to use: You just turn it on, then press the dull blade into the cylinder on the sharper, and it cuts a coarse tooth pattern. You then retract the blade and move it over half the distance between the teeth to put a much finer tooth pattern into the blade. Cutting the new teeth into a dull blade literally takes maybe 10 seconds.
The Tigers Teeth Blade oscillating tool blade sharpener made quick work of this thick worn-out metal-cutting blade.
The sharpener is small, lightweight and portable, so it’s easy to throw into your tool bag and have with you at all times. Now when I’m using my Fein saw on jobs, I keep the sharpener right next to me, and when the blade gets dull, I can leave the blade in the Fein tool, sharpen it in a matter of seconds and keep working. I think could probably sharpen each blade at least 10–20 times before you have to throw the blade out.
Does the sharpened blade cut as well as an original? I think they are very comparable in cut quality and cut speed, and they work amazingly well for what I need.
The sharpener costs $179 online, and the battery adapter is $25. If you use an oscillating tool a lot, this sharpener will quickly pay for itself. It does have the capacity to sharpen blades for hole saws, circular saws, etc., but I didn’t try those—for me, it’s worth it just for the oscillating blades.
