Yes, they are the sweet spot for solid core and even stranded (if the insulation is somewhat easy to strip and once properly graduated).
They did the job when I used them to strip Canare 4S11 (just lost a few stands with 16 strips) but it was a painful experience.
I also successfully used them with various Kimber bulk cable years ago.
Hoping that the one's Chris rec'd will be kindler/gentler when I revisit the Canare to add connectors (want fresh/clean ends for that).
I didn't gather from the pics that Big's cable has 48 insulated wires (found out when I reviewed his link) and can only imagine the sense of accomplishment involved with stripping 192 wires for a stereo pair.
I also saved his "link" to the bare 92% copper connectors/spades as they also interest me, but I do not own a crimping tool (don't know what's good/OK/waste of time).
I have a couple of copper bearing solders from Chimera Labs and another source which might be interesting to try.
