size of carry makes a pretty big difference on what your going to end up likeing. The sar3 looks great and is tiny compared to some of the other "small" busse's out there.
To give you some idea of the handle size of the basic 3 (the basic 5 shares the same handle), I have medium sized hands (9" circumfrance around widest part (across the knuckles)).
One big consideration is edge thickness. While the basic 3 might look nice - it is a tank. It's 1/4" thick and it's edge is built for abuse. The cabs:
Has one of the thinner stock thicknesses and 'right behind the edge' thicknesses. It about half the knife that the basic 3 is in terms of thickness, it will fly though things where you will fill the basic 3 drag. It also doesn't have a choil to snag on burlap
some other knives that might be worth considering:
BAD (boney active duty) - the one shown here is just a normal active duty from one of the first runs, but the size is the same. I sold it because anything under 8" should not have a choil for any reason, ever in my book. cut food netting (onions/bells etc) and bunched up plastic (pizza box wrapping, bags of chicken) and the choil was just killing me.
skeleton key is nice, but a little thin on the handle and a bit hard to sharpen being so not-tall.
The rat tail is a fantastic little knife from swamp rat, super ultra compact. one of the only truly 'compact' knives I've seen from any of the companies.
busse cultellus
swamp rat hairy carry
Busse Pork Belly Skinner and a swamp rat swamp warden
leaner meaner street, pork belly skinner, cultellus, and another option that may or may not work for what you want - the mini sus scrofa. It has the third thinnest edge and tip out of any busse I've handled next to the NICK or the CABS.
This is what you have to watch out for when your looking for knives for skinning or edc - the incredibly thick edges on some of the models. This is a standard boss street next to a standard mini sus scrofa. Sure, the boss streets stock thickness is almost twice that of the sus scrofa, but look at that tip. Just look at it. Think of what thats gonna feel like in use compared to the fine tip of the sus scrofa:
