I wanted to replace a nearly 100-year-old Wharncliffe pattern from LF&C I couldn't quit carrying as I loved the blade selection, snap, and slimness. This was the only thing I could find in carbon steel that came close. It's a little bigger at 3.75" closed, which I find "just right" for a knife.
Kinda weird the ONLY company producing a not-GEC-priced Whittler in carbon steel is Rough Ryder. Case has only released their Wharncliffe Mini Copperhead and Seahorse Whittler in stainless steel. On another note, I'm still kicking myself for not getting a wood #19 Little Rattler when they were new. $75 wasn't too bad when we're talking about GECs.
I don't get the two pen blades over the fact most have coping plus pen; not duplicated blades.
Got two others since SMKW had free shipping on all orders today.
Classic Carbon Denim Micarta Half Hawk (Loom Fixer). I decided to get it before it got discontinued and the cheap SMKW direct prices ceased; and at the least I'd be paying $20-25. Also at $15, MUCH cheaper than a vintage Case or Kabar example. Plus, I can use the RR like it was intended without babying it.

And the Classic Carbon hawkbill. I like carbon steel in my hawkbill. Klein may make good hand tools, but their Utica-made pocketknife line is a little rough. Every new one I have purchased was stiff and dull. Lower-end carbon steels take rough farm use better than lower-end stainless steels. I have close to a dozen different Utica-made knives. Only two; one a hawkbill made in the '70s (and it's not got a lock on the blade, and is much slimmer than the current pattern) and a high-end line bone-handle double lockback made for Moore Maker are the ones I'd call grat quality. I'm moving to this for cable/wire/fine pruning work; and a Byrd Meadowlark Hawkbill for farm work. I do wish SMKW would put plain bolsters on these Classic Carbon knives, however.
And all for $42.63, sales tax inclusive. It's why basically RR is the only Chinese knife I'll buy. Decent quality for a working knife (actually quite good), and it won't break the bank.
