IBC Pinnacle/Cosman Double Irons
These are a super blade and coupled with the Cosman Cap Iron they are even better. The adjustable tabs at the rectangular slot in the Cap Iron allow for the extra thick Iron and reduce that annoying backlash usually associated with thick Irons. They are A-2, 60-62Rc, double tempered and cryo treated, very well finished and have the correct width slot so that there is not too much lateral backlash.
I have a few Irons in stock and a fresh batch arriving within a week, including the new IBC/Cosman Double Iron - have a look at my site for details.
Take care and Stay Sharp,
Jim
IBC Vs Veritas & Lee Valley
The Blades that Derek has mentioned are just about the same - A-2, over 60Rc, 2.45mm or thicker - except the Veritas and Lee Valley aren't cryo treated.
Take care and Stay Sharp,
