Center Scribe?

[Mitchell Knives]

I'm looking for a center scribe to mark the desired edge thickness of stock prior to grinding. What kind of center scribe is everyone using? Jantz has one, but I don't know if it's any good.

Thanks!

You might want to check out the sale forum. There's a good looking one there, http://www.bladeforums.com/forums/showthread.php?t=627349. Patrick Randall (patrickknives) showed me how to use calipers to do it. Works pretty good. It was discussed briefly in the thread mentioned above. Those folks prefer a center scribe. Looks good.

Very simple, very fast, very effective...and (very) low cost.

I use a height gage.

you would be better off getting a set of 4" dial caliper and some layout dye. the edge scriber works but you don't have a good way to set it, you have to guess at it. i'd rather know than guess.

Hope we'll see you up at the GTG today - that center scribe will work just fine, but I think they are pretty proud of them. Should talk with Alan about how he made his, we keep saying we're going to make a couple, but I just keeping using his or using a similar size drill bit at how.

Where you been hiding Bud?? Good to see you posting!

I posted this in the thread that Phil mentioned but I will put it here. An edge scribe is more robust that calipers and will take years of abuse. It is not as exacting as calipers, but why do you need to be exact? Eyeball set your scribe to the stock's center line closely and mark from BOTH sides. Unless you happen to hit the exact center of the material, you will end up with a double line that is actually easier to grind to anyway. Symmetry of the grind is still achieved as closely as if you painstakingly measured it out with calipers....Hey we are hand grinding, no? That being said, a height gage is a very elegant solution. I am interested in trying this method not so much for accuracy's sake, but rather because it would allow me to easily re-mark my center line if needed, even after the bevels have been partially ground. You cant do that with these smaller "knifemaker" scribes. The simple home built job pictured above would allow the same thing for almost nothing, but I've always wanted a height gage

Hope the GTG went well. I had to work late yesterday, so I didn't feel like getting up early. The commercial scribes do seem a bit pricey. I like the one Alan made; I will have to take a closer look at it.
