i am by no means an expert. But i have found hemostats extremely useful. or is that function served by a different item?
A lot of folks agree with you, but I've never felt the need for them, personally. Direct pressure, elevation, compression, pressure points, and tourniquets will usually suffice for hemostasis. I might add some clotting agents,though. I consider field use of hemostats mainly useful for pissing off vascular surgeons.
