I know the A&A have made some wonderful custom pieces seen here

Do any of you folks know know of a decent factory reproduction?

A quick look at Del Tin, Denali armory, and a search on KoA all came up empty, I have a foggy memory of a Windless made Tuck, but I think it was a bit thin, and at any rate, certainly out of production.

Then Cold Steel had a Sword Breaker, also out of production, but too short at 30 inches.

Any thoughts?

Not sure if it's viable due to intercontinental shipping and customs, but Arma Bohemia can have one made for you:

You can find its entry on this page under EP36.

Might be available more quickly than A&A, regardless.
