The negative is that it is not easy to thread the wooden skewers through the holes in parallel. Therefore, I do not recommend it for wooden skewers.
The positive is that you can quickly cut the meat into small, uniform pieces. After cutting the pieces, you can thread them onto the skewers by hand or use them for frying or cooked dishes.

The holes are not aligned, resulting in some holes being very small/tight, so the size of the wood that was in the package did not fit. Only the smaller one fit, but it was too short and not useful. In the end, it took me much longer than if I had done it by hand. Not to mention that the sticks were 30 and not 32 as the description stated...
