Hmm, me haz idea....I hate it when that happens.
As posted by me, elsewhere on der interwebz, today.
"One from the 'You can't order that' files...Mid to late 1980's Randall Model #10-5 'Special' made for longtime authorized RMK dealer Jack Crider.
1. Drop point blade grind on a Model #10-5, 'You can't order that.'...
2. Blade choil (index finger cut out) on a Model #10, 'You can't order that.'
3. Hilt (guard) on a Model #10, 'You can't order that.'
4. Full-sized single finger-groove (SFG) handle shape on a Model #10-5 or #10-7, 'You can't order that.'
5. Elephant Ivory handle scales with maroon liners on a Model #10, 'You can't order that.' (or any other RMK for that matter, as of 2014).
That's one of mine, I think it's pretty special; let's see yours..."
Alternative Ivory would likely produce similar results. Idear away. As always, YMMV...
