I do a number of different saps, flat saps, soft load, hard load, all sorts of different sizes. Each type of sap may do the same thing, but they do them in different ways.
The Ulster sap. This is the smallest of the range, but by no means ineffective. Weighing in at just under 10oz and with the body being only 7" long compared to most this is tiny. But don't be put off, the position and length of the strap make this sap feel like a 9" one. The clever thing is, with it being only 7" long you can make this disappear into a pocket with no protrusion.
