Woodworking knife

Lube is especially helpful when cutting metal with a hacksaw. Paraffin wax helps, but is nowhere near as good as a product like Boelube. The stuff I got is in solid form, probably a wax emulsion. It was cheapest at use- enco.com, about $3 for a small stick. (I waited for a free shipping no minimum promo...then bought 3.)

I used a hacksaw to cut an old handsaw blade, not a circular/table saw blade, for one of my knives.

My first cabinet scraper was made from the same handsaw blade. I often use this scraper to scrape dried glue (lines), before sanding, belt sanding or scraping with a store-bought scraper.

I've never tried making a knife blade with a circular/table saw blade.

This would make the task a whole lot easier.

forever. I use it mostly for marking fine cuts. Does it pay to get a reall y good woodworking knife? If so, any recommendations?

if I have a metal cutting blade for the band saw but I'm going to check. C ould be a fun project.

two inches cut and then set it aside for now. I'll hack a couple of inches a day or whenever I can get out there. I really like how Paul Sellers uses a woodworking knife to make perfect saw cuts for dovetails and other cuts. That's what I'm actually after.

Do you have (or know a friend who has) a radial arm saw?

In the thread entitled "what is the value of a sears craftsman 10 inch radial arm saw model no. 113.29411" I described how I used to use a RAS with an abrasive blade to cut steel plates, some up to 12" wide and 1/2" thick.

I'll bet that method would make quick work of cutting a circular saw blade.

You might find this article to be of interest

He makes a good point about the thickness and I note that very few providers of such knives give that information.

For another view,

Note that both are in agreement about spear-point knives, sort of--the first finds rounding the point to be fine, the second sees it as a flaw.

Personally I find such knives a clever concept that has less utility than one might expect--I have a left and right handed set here somewhere that mostly serve as paperweights. If what you have is working for you, stick with it.

Or one of their other fine products:

A somewhat related question? What's the optimum angle for sharpening a shop knife? I've seen 22 degrees, but I wanted to check for other opinions.

For this kind of thing a Dremel with a cutoff wheel is your friend. It's amazing what you can cut with a package of cutoff wheels and some patience. Of course if you've got an angle grinder even better--same principle faster cut.

I actually did try that. It was really unwieldy but the wheel did do some o f the work. I'm still at it.

Thanks.

Gas hacksaw - only way to go!

Actually, if I was doing this (and I doubt I'd cut up a saw, they're more useful as saws) I'd cut it on the shears over at my buddy's place. It's useful having a machinist as a friend.

For a short length of hard steel that will hold an edge, you might also consider an old, dull file. If you want to get into it deeper, air-hardening tool steel isn't terribly expensive...
