VAR CD-38210-1.370 BB tap right handed thread - Compatibility question

Hey folks,

I have a VAR CD-38200 set of handles and taps for chasing threads in Bottom Brackets.

For English threads there is a right and left handed thread. The right handed thread being on the Non-Drive Side.

Well I need to replace that die with the CD-38210-1.370 because it is well worn.

QUESTIONs-
1.Does anyone know where I can get one of these? I tried Mel Pinto Imports but cant seem to get ahold of anyone. I tried ordering one from an obscure Euro distributor and 8 weeks later they sent me the Italian version. I tried the Canada distributor for VAR and they only sell the complete tool ($900).

2. Can these be sharpened by a pro carbide grinder?

3. Is there a cross compatibility with any of the other tool companies such as Park Tools?

Any help here appreciated.

Here in the NE of USA there are many tool grinders (people, not machines) that can do the work. If you are near Rochester, NY I can reference one local guy. Andy

Andy,
I appreciate that. I suspected that sharpening might be an option. Its enough to know that it can be done. Ill seek out a grinder in my local area (SF).
