Bonita Briar

[Teodor]

Hi all,
I hope you have a nice weekend.
Just finished it, fresh, made form SEM mottled briar with black ends.
This pen put a fight with me as the black end of the barrel had a sort of inclusion that forced me to replace it.

Nice weekend all
Teo.

Beautiful workmanship, as always, Teodor !!!

Congratulations !!

Would I be correct in thinking that the material is Ebonite ?

Nice pen as always. Do you have an opinion about SEM (German) ebonite vs. Nikko (Japanese)? Particularly interested in plain black ebonite as a base for urushi finishing; I suspect that there is no difference, but would be interested in your experience if you have compared them. Thanks.

I didn't used yet Japanese Ebonite, will probably use their mottled models, looks nice.
The black Ebonite I use from SEM it's called 1920, it contains carbon powder. It's harder than normal Ebonite, It eats carbide for breakfast.
My choice wad based also on location, i live in Czech Republic, it takes 2-3 days ti get it from Germany.

Do you use HSS tools then and just sharpen frequently with the SEM?

I use carbide inserts but I need to sharpen them after each step.
HSS doesn't stay longer sharp. I use HSS on parting holder.

I never turned SEM, but I use black Japanese ebonite. Cuts like butter (well, for ebonite): I never had to resharpen my carbide inserts, and HSS gets dull only after some time. Japanese black ebonite is way cheaper (12$ per meter compared to the SEM 40$) which is worth the shipping cost, colored is a bit cheaper in Germany (42 vs 47$).
I also tried Indian ebonite, cheap but it quickly dulls tools, and it has some bubbles. Funny fabric parcel though:

Love the shipping bag! Do you import your Japanese ebonite from Japan directly or do you have a European source? I found that the shipping charges from Japan make buying small amounts of ebonite cost prohibitive. I have a local source here in the U.S. (importer of SEM and Japanese ebonite).

The black SEM ebonite it's not the usual ebonite, its called 1920, it has carbon powder in it, it's completely black compared to normal Ebonite, also it's harder.
Nikko ebonite it's cheaper but adding shipping and customs its more expensive. Besides this it takes around 10 days to have it. I get SEM in 3 days if any issues i can solve it quick.

Theo, thanks for the info about SEM ebonite. It seems the 1920 is interesting only for plain black pens, right? Btw, a very attractive pen as usual...
Fred, I have no European source: I just ordered 6 rods from Japan, 134$ including shipping , that is 4.50$ for one pen, twice cheaper than alumilite.

Or for Urushi. I'm tempted by the Nikko Red.
