An interesting kindling splitter... https://youtube.com/shorts/b5GDmkM1OMw?si=34La3zr1MGq23Jky Available commercially; or make similar DIY...
I really could use a product that gives me help producing kindling. I need to find something this Spring/Summer...
I have one of these: Well something similar to that any, works well, but not well suited for really small stuff.
I just use my axe or hatchet for smaller stuff which seems to get the job done pretty quick. In looking at the OP's device I can see where it will save some time and energy though.
