The poor man strop kit is good.

But one needs to remember that balsa is a natural wood material and is subject to any of the issue that all wood is subject to. So care needs to be taken to make sure those issues don't become a problem.

As to leather strop the poor man strop comes in the fashion that the old barbers preferred without handles. This means that you grip the very edge of the strop to pull it tight. This would put your hand in a position to be cut but really it should not be an issue cause you should be turning well before that point.

Different grips come in and out of favor. When I first join the barber style was a favorite. Lately it has been D rings. Then you have strops like the Illinois strops that have full leather handles

Everyone has there favorites and you can find inexpensive strops in all versions.
