Well no, not really graves, but the newly turned garden beds rather look like that, don’t they? And it got you to read the blog post, didn’t it?
I got myself a shovel, a new one instead of a second hand jobber, only to find out that shovels are sold blunt here. I bought a V shaped shovel (“spade”) but the metal edge is rounded. Store clerks look at me like I have 2 heads when I ask about getting them sharpened, and assure me that they still push into the soil. Well, yes, they do, but with a lot of extra effort. I finally found one old timer who said that lawnmower shops can sharpen it for me.
