I will find out this weekend how it works, the Cat’s Claw is getting out of control again and needs trimming, that will be a lot of good abuse to see how well it will hold up. I usually use a utility knife with a disposable blade to cut it off the block fence, so we will see how it does. Plus I will be putting in a corner post for a new pergola tomorrow morning, there will be plenty if ivy to saw through around there.
I have usually used an old Lee Enfield bayonet for weeding, it started off blunt and is slowly getting polished to an edge. That is a trend I have been noticing with British military accoutrements from the Victorian and Edwardian eras, may be of dubious utility for the professed purpose, but make for excellent gardening tools.
