Unnumbered Carborundum hone

[superbleu]

I just got this hone, but it doesn't have any model numbers on the box or hone. It definitely says it is meant to be used on razors as per the label on the inside of the lid.

As we discussed by PM previously, if you can give me all three exact dimensions, I can probably give you its ID number. Unlike my previous estimate, if it is 4 inches long, it might be a 103. That is, as long as it is 2 inches wide.

Ron, it's 4" x 1-1/2" x 7/16th" thick.

it is most likely 103.
101 or 100 are longer.

OK, in that case it's my favorite Carborundum, the 102.

I have several of them and they are all my favorite!

Awesome!!! Thanks Ron!!! Any suggestions on cleaing/lapping it? And how to best use it?

Is it greasy or oily? It seems like many of the Carborundums ended up that way. If so, I would start with oven cleaner. Spray it on and leave it for a half hour or more and then give it a scrubbing with a stiff nylon bristle brush. If need be, repeat it.

Carborundums are incredibly hard and will eat DMT plates. Don't lap yours with any DMT other than the XX plate. You can also use coarse sandpaper and if you do that I would start with about 120 grit. Realistically though, because they are so hard, they don't dish and are all close enough to flat. Barber hones don't need to be perfectly flat and almost any of the lower 100 series Carborundums, like your 102, will be close enough to flat that it will be perfectly useable without lapping.

For using it, hold it in the palm of your hand with your holding hand straight out and the hone just sitting on top of it. If you instead choose to hold the hone with your thumb and finger tips, then make absolutely certain that your fingertips are BELOW the top plane of the hone. If you fail to do this, then your fingers will be slightly shortened! Like the Swaty, you can use the hone dry, with water, or with lather. I definitely prefer diluted lather as the soap breaks the surface tension of the water and prevents it from beading and being pushed off of the hone. Just do 4 to 6 laps for touch ups.

I just threw together a "family photo" of the low 100 series Carborundums.
Left to right they are 101, 101a, 102, 103, 104, 105, and 106.
Their lengths in inches are 6, 5, 4, 4, 3, 8, and 4.
Second photo is just the 102 with a razor for scale.
