I give this hori hori 10 out of 10 acorns. It's taken me a while to write my review because I've got little ones at home, and I don't want to accidently leave a giant, sharp, serrated shovel lying around...and I tend to forgetfully put down things that I'm using, and I didn't want to accidently leave this some where they could get it.
But, now that I've had a few chances to use it, I can say without a doubt that I love it. I used it to dig in the half-frozen ground, and it did great. It's very sharp and comes with it's own sharpening stone to keep both the smooth and serrated blades sharp. That serrated blade sure is sharp, too! It came in really handy when I was making a mallet and
spoon for the roundwood woodworking
PEP badge. It's a lot easier for me to handle than, say, a folding saw or even a pocket saw. It bites rather nicely into the
wood. Due to being curved, it's not the best for cutting deeply, but I was using it to cut a centimeter or less to trace out areas on the spoon, and it worked fantastically for that.
I love that it is full-tang and that it shows how deep you're in the ground by inches. I can barely wait for planting season and being able to put this awesome thing to more use.
I wish I'd gotten more pictures while working with it, but here's it with the beginning of my mallet. I'll try to update this with more pictures as I take them!
