Electric rotary tools are popular. I
read an online discussion about the
little circular saw blades that many
of us use. It appears that some major
manufacturers no longer produce those
attachments. Hmm, why would that
be? As it turns out, nearly everyone
in the discussion had hurt himself
or herself on unprotected rotary saw
blades at some point. Yup, even I have,
and more than once.
They’re really useful, but an
unprotected spinning blade is as
dangerous as it gets! I often substitute
an abrasive cutoff wheel for the little
saw blade. It’ll cut balsa fine in a slow
and controllable way and is less prone
to kick out and bite your hand.
Building, Not Bleeding
I’ve always used single-edge razor
blades for my model work, but most
builders prefer a standard hobby knife.
Either way, I endorse the old Boy Scout
advice that a sharp blade is safer than a
dull one. I toss my little blade and grab
a fresh one when it begins to load up or
become dull. The minor expense is worth
possibly avoiding an injury!
Hobby-knife blades are meant to be
disposable, but it is easy to resharpen
them. With practice you can improve the
edge beyond factory new. I had to buy a
second honing set because Sweet Diedra
claimed to have found a loophole in our
marriage vows that lets her swipe my
hobby tools for her craft room. She likes
her #11 blades nice and sharp.
