I use a Dremel tool with a thin cutting disk just to do even spaced marks on the blade and then come back with the file and the end result is almost as perfect as from the factory, just take the time, don't rush it, and if is done well it won't take you more than 6 or 7 minutes. Good job by the way! and a great piece of advice for anyone who's not discovered the trick, this is one of the easiest hacks that will save you a couple of bucks and unnecessary wasted time on trips to the hardware store.
Great idea. I use an dewalt oscillating tool almost everyday. When I break a blade I weld it back together. I'll sharpen all my old blades I have saved .
Interesting...given how expensive the better osc tool blades are... fun DIY and great extension. I have only purchased blades in person at big box but they seemed expensive.
Sharpening blades (of all types) is a great way to save money, especially if it keeps the job going by saving a trip to the store. I think most professionals (contractors) make sure they have plenty of new blades on the job and don't use their time sharpening, but for the rest of us it just makes so much economic sense. Thanks Bob, I really was surprised how easy and quick it was to make new teeth.
It worked out very well. The blades are hardened Bi metal steel, so as long as you have a decent hardened triangular file it makes quick work of it. Bob
Good idea. I've thought about it, but never got around to trying to sharpen one. I've saved all my used ones. I have several Fein /Bosch Starlock blades that this technique should work well on, and those are $20 a piece!! 😖
You will be surprised how sell it works. I noticed some of the fancy (Japanese Tooth) blades can't be sharpened, but if you grind off the fancy teeth you can resharpen them. Thanks for commenting. Bob
Some blades then are harder than the file itself as I found out this file wouldn't even scratch the blade I've tried sharpening diamond coated is the best.
Could be useful in a pinch . I'd be curious as to if the edges of these blades are heat treated for hardness from the factory and how much area is heat treated. That would definitely limit how many times this could be done. Bug like he said in the video the blades aren't all that expensive. I bought a few multi packs when I got my tool so I have never had to worry about it . Nonetheless pretty neat if you had to do it in a pinch.
Good Job Bob. I think this is a great Tip for people i never thought of that and I agree with you Nicholson files are very good files I have a couple and they are the best files I have. Hows the boy doing? I have a question about a different video. The oil seal you put on the Honda governor shaft did it work long term? I have 2 Harmony HRX and of course the shaft is leaking on both mowers don't understand why Honda doesn't put seals on them. Thanks and Have a great weekend. God Bless!!!
Yes, this worked out well. The oil seals work for the life of the motor. Please contact me at doublewide6repairs@gmail.com I don't think they have PM available here anymore. Bobby is doing well just pitched a baseball game.
What if the blades are carbide or high speed steel ? This will work okay if its just high carbon steel blades otherwise the blade will be really hard to file otherwise.
Dill Wiggle -- (high speed metal blades with teeth) I would sharpen fine angle grinder or moto tool. Watch not to overheat blade while sharpening. Or hand diamond file. Cardiumum or diamond bland blades Can not be sharpened and become dull or finer grit with use. Try to shift grit back and forth to use blade evenly These blades last longer. LOVE
The tool is cheap and the blades are overpriced. If you take a new blade and heated with a torch and dunk it into oil will that harden it and make it last a longer time ??
