Let's talk about blade sharpening?

[Glades Cat]

Retired blades make good knives. Cut to rough shape, flatten, grind to shape, sharpen, drill and make handle.

I understand your point now...
But which angle offers the greatest resistance of blade material to the material being cut, or something else?
I am convinced that the 45° is stronger and will suffer less damage...

 

[MParr]

I don’t follow a set angle. I follow the original blade angle. After a while, you just know.

 

[Bange]

But original from the factory or the way it comes to your hands to sharpen?

For cleaning blades, I simply put them in a old drain pan, & add some tap water to barely submerge them, & let soak 1/2 hour,
remove & simply wipe clean. The water does the work & makes cleaning so simple.. No grinding debris dust to breathe.

Sharpening, I use a mill file & finish with a flap wheel... The OE blades I have are Marbain Steel ( heat treated ) so they hold an edge very well..(30* x .030") I also use a set of Oregon blades, & really like them. I pivot balance, & works for my private use.

Very ecological... but water does not remove the rust crust and in these cases you must use something more aggressive...

One question...

A = dull blade that needs sharpening.
B = Use of an appropriate power tool for sharpening
C= Another form of sharpening with a specific tool.
Consider B and C after many sharpenings...

What is trend B or C?

Mine don't have rust on them..

MParr and Hammermechanicman.

What is your sharpening angle?

I match the angle of whatever is on the blade. If the blade is so bad I can't tell I use 30 degrees. In the shop I see dozens of different blades

Dang! You got a $3k Burrking.
Totally jealous. I just have the All American sharpener with an angle grinder with 36 grit flap disks. I built a wire brush blade cleaner from a table saw motor but it makes such a mess I don't use it much. If my shop was bigger I would get something better but I am so crowded now no room for anything new.

Actually in my case I split the cost with my nephew who runs a stump removal business, and the same grinder uses the diamond belts so he can sharpen his carbide stump grinder teeth. Those belts are $134 each. but my 1-1/2x60 36 grit ceramic sharpening belts are $10.99 and will do about 80 blades before replacement.
