Picked up this top of the line 5/8" hollow ground Challenge Razor Works in "bamboo-esque" celluloid with genuine pearl covered tang. Checked an old 1916 hardware catalog and this model was the most costly of the brand at $54.00 per dozen, or $4.50 each. That amounts to approximately $87.00 in 2015 dollars!! Hope it hones up well.
