I don't have but two naked knives, the others are a matter of preference for the particular knife. I have been around collectors enough to know they ALL are eventually taken by an item that isn't exactly perfect but still desirable. I buy things I want and then try to upgrade...I've applied that philosophy to numerous collections over the past 50 years. With Randalls I've learned it's nigh on impossible to find older sheaths. I was talking with Jason Randall a few weeks ago and he told me he thought miss-matched sheaths was a BIG collector issue. And newer guys like myself don't always know which sheath is the right one.

Example; I bought two nicely engraved, matching 1 and 2 Randalls
from the heir to an estate. Hos benefactor had purchased the pair from dealer Jack Crider was all the heir knew when I bought them.
I didn't even know who Jack Crider was at the time, and still don't know who engraved the knives. Fortunately I was able to buy new sheaths, but now I know the knives are 1969-1975 vintage and require JRB sheaths to be proper.

Hope that answers your question. Be good, be safe...and if necessary, be good 'n safe.
