Custom designed tanto knife for Aikido training. I put the knife vertically on the plate for try but if you want to get more durable knife you should put the knife horizonally and use rafts and supports.

Model's Dimensions:

X: 19.99 mm
Y: 300.00 mm
Z: 34.24 mm

Edit: Added soft-edged version. I think it is safe for children. If editing is needed again, if you leave a feedback, I will gladly edit it.
