This is dibbler (dibber) to produce a transplanting hole for mini (3/4" x 3/4") soil blocks. I think it works about right. If you move in a circular motion as your 'dibbling' you will have less soil compaction. I dibble so the top of the square is just below the surface. I then use the base of the dibbler to compress the soil around the mini block.

Please provide any feedback as I would love to improve.
