Well Santa brought me some new goodies this year so I thought I would share my thoughts about them.
Here is the Grizzly digger from Dirt Digger Tools: http://www.dirtdiggertools.com/the-grizzly.html
If the Lesche Model 76 and Model 31 had a baby, this is what it would look like. The model 76 has the serrations for easy root cutting but has always been a pain trying to scoop dirt from the hole, the model 38 is great for scooping dirt from the hole but has no provision for cutting roots. This too does both! I have put this thing through its paces this week and it has performed excellent. Especially with this NY weather as the top 1" or so is frozen solid. I'm also recommend Buzz Wilsons Raptor styel sheath for this tool as it fits it like a glove and is easy in and out of the sheath. Here is a pic of it between the 2 Lesche models.
