Enter the age of the electric scraper sharpener!
Let’s step back a moment and look at the evolution of sharpening your scrapers — a
critical component of making fast skis, and also important to working efficiently. In
the old days, we could choose sandpaper, drywall screen, or even a giant panzer file
(please, no!). Later, several manufacturers came up with hand-held or bench-mount
devices that were manual and used a blade over which you pulled the scraper. These
devices had varying degrees of effectiveness, but in my opinion were still not even close
to the sharpness and consistency one could achieve with drywall screen and a 90-de-
gree angle guide.
And so I’ve personally never recommended any method of scraper sharpening other
than drywall screen and a guide — until now.
The Ski Scraper Sharpener:
Bob Harris, owner of Mantac, set out to
make a highly portable electric scraper
sharpener that would work for everyone,
everywhere — athletes, clubs and coaches. His design features a carbide cutting
blade, a power supply not unlike your
laptop, and the ability to connect different cords to that power supply so it works
globally. It’s the middle weight in the test,
made of what looks to be a three-inch by
four-inch block of Trex (recycled plastic
composite wood). The blades are mounted
on a drum, which is shaft-driven from the
Tri1: Made by Paolo Trione, and sold in the United States by Marjon Cernigoj (former
USST coach and now chief trainer for the Russian women) this device is expensive,
precise, and lightweight. It’s aimed squarely at current users of the Tri1 side edge grinder (i.e. professional technicians), and designed to plug in to the same power supply. It
can also be run directly from any 12 to 18-volt cordless battery. It’s by far the lightest,
and uses carbide blades on a disk, very similar in appearance to the router bits we’ve
seen used for boot lug modification ($350).
