Utility linemen’s knives

[ADBrown]

Having retired with 45 years in the electric distribution utility field (rural co-ops), I’m curious if any here are linemen, and if so, what knives do you use? We had either a Klein skinner or a lockback (eg Buck 110), or usually both. If I’d had the choices then that I have today, I might’ve opt for a CRK Umnumzaan in tanto. What do you new generation of linemen use, and why?
Thanks, Allan
