Back to old school tool use.
I try to explain what I know to other people I work with.
If they are the type that likes to learn then I will continue teaching.
Today I taught the young man that works with me the term kerf with saws.
Why is it a saw can be sharp and have difficulty cutting.
Hacksaw for this example.
The blade teeth were sharp but it was getting difficult to cut.
It was the kerf wearing thin on the blade.
I explained and tossed the blade.
I also told the guy about how you can get a tool to set the kerf on saw blades but not hacksaw blades.
They are disposable.
The kerf is the teeth are cutting wider than the body of the saw.
This allows the rest of the blade or body to pass through without friction.
