Gifted Dubl Duck

My best buddy just gave me this Dubl Duck hone.
It looks unused. No flaws.
I'm thinking about using it but have a few questions:

1. Should it be lapped? I could send it to a buddy for that as I don't have that tool.
2. I read that the course side is around 4k. And the fine side around 10k. Is this your experience?
3. Are these good hones? Or would you keep it for historical/collectors value?
4. Any specific tips on these hones?
I now have a hone and a paddle!
Baby steps!
Thanks for your input gentlemen.

Don't lap it, Mike!

2nd that motion. !!

Well dang it guys, I was expecting to see jaws dropped and get PMs offering small fortunes..
Wow MikeT! You are now the coolest shaver that side of the Rockies..
With THAT stone, you only need to touch the blade to its immaculate surface and it's immediately "Sharptonn Sharp" upon contact..
No I will not trade it for your NOS Escher. Wouldn't be prudent. Not gonna do it.
Just don't even ask.

Well, I'll except some tips that are specific with these little barber hones... IF that is, it doesn't spontaneously sharpen my blade Sharptonn Sharp upon contact.
:dropjaw:

Har! I have heard they are good barber hones. Seems you use it dry.
You have the instructions, Mike. What do they say? 8-10 light strokes? Give it a try!

As Tom said, read the instructions. I think standard for barber hones are 8 to 10 laps. Some would use lather, some water or just dry. Water is hard to put on imthem because it pools up and just wipes off. Ive done lather on the one i have.

Hope you don’t mind me hijacking, Mike, but why shouldn’t it be lapped? Does that go for all barbers hones?

Most of these synthetic barber hones are just an aggregate of materials and if you lap them many will start to come apart on you. Newer Synthetics are different and can be lapped of course.

Okay sounds good, I'm gonna go for it. Short X.
Though a dry hone just doesn't feel right to me, but then again my experience is limited.
Maybe dry, and then water with a drop of dish soap..
Though with this breaking up.. Maybe the water and soap would increase the chance of deterioration?
I'll try it out and report back.

Thanks for the input guys! Much appreciated.
Hope you're all enjoying the beginning of the winter holidays.

Edit: Hijacked my own thread with different subject. Bad habit. Erased.

If you lap them, you change the original characteristics. The way they were surfaced on either side.
Also, I find they like some 'burnishing' with use. Sort of like an Ark.

So they are not for honing your razor, but refreshing the edge. Sort of obsolete IMO as most do not go beyond 8k.

A good-shaving razor which has begun to pull a bit should be tried. If honed with tape, tape should be used.

Okay cool, I'll do some burnishing.
A couple questions:
What is best to burnish it with? I've read the side of a screwdriver, but was wondering if something with a flat surface is better as to help flatten any imperfections...?
Also, is it true that using water while burnishing is better?

No no, it gets burnished when you use it on RAZORS, Mike!
