Been a telephone man most my adult life, (started when I was 20) including over a dozen years in the field climbing poles, and still have my lineman's belt, and hooks... Lineman's belts are MUCH heavier than today's rock climbing harnesses and really wouldn't be practable dragging to a tree stand every day, although to set up a semi perminate stand (like a once a year deal) they're okay, but to lug one around all the time depending on how far the walk, would be a pain...
Some of those tree trimmer setups are pretty cool, but don't know much about them as to weight...
My linesman's belt was top of the line back in the day and believe I got it from either Bashums's or Halls out of Grove City, PA, both companies are located there, or used to be...
Now ya have me thinking about mine... Wonder if my belt is still stashed in my mom's basebent, or she gave it away like a bunch of my stuff...
If there, wonder if it still fits or shrank too much...
