A thoroughly well written review http://www.xtremerigs.net/2015/10/20/mayhems-borosilicate-glass-tube-review/ impressed would be the least of my words to use. Thank you.
You need to come here though and snap a few thousand pieces of glass then you become an expert at it ... lol
I found these cutters and feel 79014 may be useful, particularly if one wanted to cut a short piece that provides small leverage at one end.
Any experience with, or knowledge of them?
