The last versions of the #6L and #5L look just like the #6 and #5 handles, but with a wider collet slot to accommodate thicker material blades.

The first version of the #6L apparently has a "rounded" non-hexagonal handle unlike the standard #6 handle, per Earl's 1952 catalog posting.
Interested in any #6L/#5L.
Have been watching for week but no luck. Most likely "Needle in a Haystack" scenario.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
