First time getting my blades sharpened on my DeWalt planer, #733......took
it to a local guy, $25, sharpened together as a matched set.
Bought a new replacement package of the same blades on e-bay for $31
and $8 shipping.
Guess its cheaper to sharpen, but not by much. This guy had professial
equipment to sharpen blades and was only 2 miles away. Got 3 sets now,
should last awhile.
Guess my question is, are those disposalbly blades any cheaper. I think the
newer 3-bladed DeWalt is that way; not sure. My planer works great, just
Gotta clean my shop, spring is almost here...outside work......yeah.....
You can sharpen these yourself with a small layout for a piece of plate
glass, some fine grit papers and a piece of scrap hardwood 12" long x 3"
wide x 1-1/2" thick.
Scary Sharp method works very well - now all you need is a holder for the
blade. Take a piece of hardwood, face joint it so you have a nice flat
surface. Now make a bevel cut in it down the center at the depth needed so
the blade edge sticks out about 1 thou. The bevel angle is the same angle
of the blade and the width of that cut is either 1/8" or 3/32" (full blade
or thin-kerf blade). I forget which it is since it's been awhile since I
made mine. But the depth is not critical since you will be using a paper
shim that not only works to hold the blade in the slot but also to shim it
With the blade in the slot and the blade protruding ever so slightly, place
two sheets of paper, lengthwise on a piece of glass or use your jointer bed.
Use some 3M spray glue to hold them in place. Now use Scary Sharp to
sharpen the blades. I used this method for about 3 sharpening's as I recall
then found a deal I couldn't refuse on a Makita sharpener that has a holder
for these type blades. Works okay and sharpens the blades okay but it's
actually easier to use Scary Sharp than it is to get the Makita set up and
Wide enough to comfortably hold and keep blade at proper angle
Add Scotch tape to blunt edge of blade to shim out the blade. Scotch tape is
Be sure each end of blade protrudes equally or you'll end up with a wedge

Time to make it - about 10 min. Setup time - 30 sec to spray some 600 grit
paper to glass or jointer bed. Savings each time - $25
Barry, do you not leave them in because:
1. they don't cut as easily as blades w/o the backbevel
2. you want to save them from nicks and dulling while cutting
predominately tear-out free woods
3. you have a 735 and it's just so darn quick and easy to change the
blades out, so why not? :)
The disposables used to be about $30 per pair 6-8 years ago. I could have
my blades resharpened for 75 cents per inch back then. So back then it was
a wash. Now that most of the portables use disposable blades I believe the
price of the blades are going up.
I reshaepen my own blades/knives now.
