How to Sharpen and Repair Old Sawzall Blades

[Baz]

I was wondering about this so found this video with recommendations.

I have a ton of old sawzall blades and most are still good, meaning they have life left in them. Hate constantly buying new ones just to make sure I have a fresh blade. I'm going to look into his technique for sharpening.

what's your address?

I'll send you a couple of pounds of them - you can send them back FedEx

I really think you are on to something there, pal. That's your retirement business. Just think, you will never have to leave the house to do this. Webbie and I will send you our blades. My problem is the bend up blades. Since I pay for all the blades, one hit and it goes onto the floor. Those bastards don't even bother to bend them back jsut to finish the cut. I think the biggest mistake is the quick change mech. on the saw itself. Its easier to turn, tip the saw, old blade falls and insert new and go. This happens faster then I can take a drink of water.

getting them dull is usually not my mode of failure. letting the blade punch into the thing i am cutting, and bending the blade is the usual mode. me and the reciprocating saw: like kerosene and a fire. something bad is about to happen.

having said that. i would under no circumstance sharpen a blade like that.

Yea, sharping a used Sawzall Blades is something I might do after the zombie apocalypse, but not before.

[RWebb]

it would work if you could buy a robot sharpener for cheap

otherwise, steel can be recycled

the good ones are crazy expensive, but anybody that is in the trades will likely find it more economical to simply replace a used up blade. the other problem i see if often one will be missing teeth entirely after some abuse so it might not be as effective.

im bored cause it's so smoky outside and don't want to go out so i watched the entire thing and still can say thanks for sharing that. i was entertained for nearly 8 minutes..

Every time I have to cut the lower control arms off a Cayenne, Taureg, or Q5 I do the cut the tip off the blade trick.
I can easliy go through a 10 pack of blades by the time I saw through all 4 bushings, and camber bolts . It only uses the top inch of the blade, but tears off the teeth fast. I use those really long blades, and just cut them down as they dull .
It really saves on blades

That's what he is showing. That and refacing the bimetal tips with a thin blade on an angle grinder. No news here, carpenters have been doing this ever since a recip saw was available.

and reset the teeth?

I was a carpenter for ten years and I dont think iv ever bought blades. I still dont. Always just sharpen them and make new ends. For metal blades I find them on the ground at the junk yard. The wood blades sharpening with a grinder start to get shorter and shorter life after 3 or 4 times because the original teeth are gone you have to make your own curf and to keep them even gets difficult. Anymore I avoid using the sawzall as much as possible the grinder and circular saw work so much better. Alot of people avoid them because they are afraid and dont have enough experience. When I was doing carpentry there was a guy that only used the sawzall he was afraid of the circular saw. Eventually he got the hang of it.

I must be using mine wrong, as it’s not the tip that wears, but the center section.

I have to say, my Dewalt cordless sawz all is fantastic, along with my cut off wheel/grinder. I keep 5-6 batteries and 2-3 chargers in my truck, along with a tool bag of Dewalt tools. Makes life so much easier.

The question isn’t how. It’s why?

[RWebb]

to use in a knife fight
