'Lo all,

Here is a link to said Kerf Starter:  http://www.glen-
drake.com/Thin-.020-Kerf-Starter.html">http://www.glen-drake.com/Thin-.020-Kerf-
Starter.html

Here is the text describing the tool:  The thinnest Kerf-Starter (.020) works
well for Japanese and other very thin saws. Like the other Kerf-Starters, it
removes a shaving the same way other scrapers remove shavings, leaving a shallow
kerf that captures your saw. Use the Kerf-Starter with a square to layout square
lines across end grain and with the long grain. You may also use it to layout
one part of a joint from another as in laying out dovetail pins from already-cut
tails (offset the tail piece to keep the kerf in the waste).

I am very unclear about the meaning of the parenthetical phrase in the last
sentence.  Derek, can you elucidate?

Cheers,
John

I'd use this with whatever grind on the tip that worked best

Cliff, 

The only problem with that "knife" is that it is way too thick. Unless you are
using a pit saw. Don't mean to be mean about it, it just won't work for fine
tolerances.

As is probably. But it seems to me that if you grind off the tip on your 
hand-crank grinder, and reshape the 'off' side as needed, a hook of the 
desired shape & size could be formed. For the price, it might be worth 
trying.

Here is a knife that has been in my shop for ever,  It is marked “Red Devil”
with no number.

I use it to clean out fret slots on a guitar before installing the frets.   I
ground it down from its original .032 to .022 or so to fit the .023 fret slots.

It has a flat edge to it already and will be easy to sharpen as a scraper

Ed,


That looks like an older version of the Red Devil 1170 Plexiglas Cutting Tool.


I have a similar tool with a brazed carbide cutting edge; I think I bought it to
work with Formica (TM) laminate.

Yes, that is what it is.  I have one I keep precisely for cutting
plexiglass.

Good call Don!
