I usually use a kitchen knife that's been laying around my workshop forever. I use it mostly for marking fine cuts. Does it pay to get a really good woodworking knife? If so, any recommendations?

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

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.

If you use a screwdriver, it will not be tempered and will not hold a razor
edge. Saw blades are differentially tempered, which allows the teeth to b
e very hard and the spine to flex. By the time you cut the teeth off to ma
ke your desired blade shape, you are in untempered, soft metal.
I made a simple one with a sawzall bi metal blade and it works like a champ
. Can't put my hands on it as I think I was using it to trim molding and i
t walked off a job. Nonetheless, it is an easy and fun project. I didn't
make the double point model. Plenty of good examples of marking knives pro
Lots of home shop guys and weekenders do it. There are plenty of
resources on the Internet about it. Hardening is fairly easy, getting
the proper temper not as much.
One thing to note is that the composition of the steel is as important as
the hardening process. Some steel will never be suitable for some
projects. (Just like you wouldn't use basswood for a hand plane sole.)
Play around with what you have if you want to play, then buy proper
material when it comes to make some real ones. I made a few knives with
hacksaw blades, and they work but are really too flexible to be good as a
knife blade. (I never did mess with the temper, though. It might help.)
I have one made from a band saw blade the blade was 1 1/4 inch, my dad
made it he worked at JI Case (formerly IH) prototype pattern shop. The
band saw was for sawing stuff in half for cut away displays you could
literaly drive a tractor and cut it down the middle.
so you won't be able to cut the saw blade on your band saw with a metal
blade. It will burn the blade, as the speed of a wood working saw is
really way too fast. That said, it's still possible, since it can be
done with a friction cut.

I didn't have a metal band saw blade so I tried the hacksaw. I got about tw
o 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. Th
at's what I'm actually after.
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.)

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.

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