I'm a little embarrassed...
...to admit that when I stopped playing pool back in the early 70's I left my plain jane Gina leaning against the wall in a cheap, nylon case with no support on the top shelf in a closet.
35-40 years later I take a look at it and am sick that it's bent, really bent.
I get the courage to take it to Ernie and ask him if he can fix it. He raises his eyebrows, shakes his head and rubs his hands several times up and down along the length of the butt and says he need to cut it to tell me.
It's pretty much worthless as it is so I say ok and he cuts off the wrap, walks over to the band saw and cuts it at the top and bottom of where the wrap was just like the video posted by the OP.
I'd been away from the game for many years and wasn't sure what his shop would be like, foolishly thinking he might have a bunch of cues on a wall ready for instant sale (LOL) but I do ask if he has anything readily available. He laughs and politely says no but he has a customer who's unhappy because the cue he ordered is taking too long to finish. The guy is calling every week and Ernie's a little annoyed so he tells me I can have the guys cue and he'll send the guy his money back with the money I give him. I have no idea what it is but say sure and write him a check for the cue and my repair.
Three months later he calls and says my cues are ready. He's replaced the wood in the grip area, refinished the forearm, turned the butt so it's white as snow, new shaft and wrap and it's like a new cue.
Here's a picture of Ernie from around that time holding my original cue, the 14B I lucked into and the abalone merry widow he made for Junksecret that eventually ended up on Ebay that I picked up as well.
So yes, you can cut some cues in half with a happy ending.
Best to you all
