Found a few on Amazon. Some very very expensive ones too!

Yes I saw one on Amazon for £134!

Hmm...was that the shovel that the U.S. Army was infamous for? And why would they need a short-handled border spade, anyway?? ;D

The army used them so that they could dig trenches without having to stand up to dig and be a target.
Don't think Amsterdam's friend will be in that sort of danger.
There were cheaper one on Amazon and Ebay.
Charlies in Shropshire do not appear to stock them.

Thanks Owdboggy. The reason she needs a shorter one is her borders are higher up. She told me she’s been looking for ages. I have gifted myself a ladies border spade for Christmas!

Good thought, Owdboggy, and probably true. I was never, admittedly, in the Army, but we did use standard surplus trenching tools (Korean War vintage) in Boy Scouts, and they were a smallish round point shovel head on a short, folding handle. When locked in the fully extended position, it likely worked much like a short handled border spade. A lot cheaper than the $400 shovel of American legend, too.

Burgeon and Ball short handled spade are the sort that Monty has, or very similar anyway.

Thank you Honeysuckle. 👍🏻
