All the knives offered in O1 are available in stainless steel.
Some limitations on that. The bigger blades (12s and 13s above 8") are not available in SS. Even that "rule" has a caveat: 12-9 no SS available, "12-9 14 grind" SS available. (see posts #2 and 3 of this thread way back on page 1.)
What about the opposite? The other way? I know that the 17 is only available in stainless steel but what about the #28 or the Fireman? Are they only available in stainless?
As a general rule: if it is offered with SS standard, you cannot request non-stainless. I can't think of any exceptions to this rule but one or two may exist.
