I’m told these are the guys who post without photos. Photobucket
I apologize for this post. I had one going and was about to post a couple phots, but lost it.
Here’s the Saw blade.
It’s a DeWalt 10”x60 tooth fine kerf for finish work. However I used it on every thing and its burnt. You can see in the photo.
I was asking about sharpening the blade and two guys who sharpen for a living responded. Maybe they’ll come back? Here’s the blade.

What are the pictures supose to show us ? All I’ve been told is if a certain amount of teeth are badly damaged or missing then it’s time to just buy a new blade, sharpening isn’t worth it in some cases. It would be best to take it to a local sharpener so they can look it over more closely and let them evaluate it.

To be honest with you I would not even bother with sharpening this one. New, this blade will run around $30 which is about what the sharpening will cost you. When sharpening costs exceed 1/2 the value of the blade it is more cost effective to simply replace the blade rather than trying to extend its life. By the way I bought one of these some time ago when I needed a blade in a hurry. Made a couple of cuts with it and put it back on the shelf.

Cleaning is very good advice. Those DeWalt blades like that have really small carbide tips to start with (and to be quite honest lower grade carbide, and not great brazing to the body). I have sharpened plenty just like it they seem to be popular with the local building contractors. But they do not sharpen as many times as other brands/styles. I don’t agree they are throw aways unless there are chipped/missing teeth if you have someone local who knows what they are doing. At my shop it is $.25 a tooth, so $15 for a walk in…but if you have to mail it someplace that is equal to the sharpening costs there and back unless a guy sends a whole box of stuff.

OK, onto the nail on the wall with the resto of the blades.
It took me a year or more to get this old Farmhouse in pretty good shape (inside and under) and I went through a pile of blades for the Skill saw and this sliding Miter saw, and (my go-to guy) the Sawzall.
I’ll bet there’s 25# of those blades down in the barn.

Thanks guys. I’ll just get one more.

Use over cleaner on those blades and you will probably see them
cut better for awhile. Carbide blades often stay sharp and cut
well for a long, long time, but if you don’t keep them clean the
won’t perform well at all.

I’m with the others on cleaning. A clean blade makes a real difference.

I’m not sure I understand the “just throw it away if replacement is more than half the cost” idea. Even a cheap blade can be sharpened two or three times. If sharpening is $20 and a new blade is $30, and you sharpen it three times, you’ve saved the cost of one blade, and kept three blades out of the landfill.

I’m going to clean it first. I’ll spray the Oven cleaner on this after noon when I go down to the barn. Hope it dont rust the blade to death.

I never throw anything on the landfill unless its absolutly of no use. I re-cycle evertyhing. I use the old saw blades for several things. They make good scrapers, straps, hangers….etc.

Sharpening us usually a $15-$30 option. New blades are usually cheaper on sale than sharpening. I originally thought I might have the magic here in my barn, but the experts have convince me other wise.
Thanks all.

Thers a fluid you can paint on the blades and is safe non toxic it does nothing quickly.They are best left for a few hours between each aplication but it brings them up really clean. After all these blades may be just gunged up and that’s what is causing the most of your problems. I have also heard of people using oven cleaner on blades but have never tried it if you wish email me and I’ll find the name of the stuff for you to try.But perhaps you should also work out how many board feet and hours of use the baldes had it not used a great deal the blade should be well worth cleaning.Alistair

I’ve never had it cause rust. Carbide doesn’t, in my experience,
rust at all – and it’s what does the cutting. I’ve used over cleaner
on bandsaw blades too.

Regular cleaning of blades with soap and water makes oven-cleaner
less necessary. I use a stiff-bristle nylon brush to scrub off the
pitch after the soap has softened it.

Perhaps a quick coat of a paste wood floor wax would prevent the rust, like it does for cast iron tops on Tablesaws, bandsaws, jointers, drill press, etc.
