I just got two strips of leather in the mail. both 3"x42". one latigo and the other english bridle. both are quite thick. whats the best way to cut these? would a common utility knife work?
To add to what Tony said above, there is a tool I use on thick leather that shaves a slight bevel the sharp corner. It looks like a little V shaped chisel. I bought mine second hand on ebay. Tony's way is probably easier for you if you are only making a couple though.
Clamp a straight edge or square across the leather, use a fresh blade in your utility knife and do not try to cut through in one pass unless you want the cut edge running at some odd angle. The knife will wander if you try to take to large of a cut. if cutting a light colored piece of leather like veg tanned wipe the protective oil off of a new blade first or else you will lightly stain the edge.
With the finished cut piece laying on a table take a kitchen spoon and run if firmly down each long edge to slightly burnish it and break the sharp corner. You want to mash the very corner down ever so slightly to make a neater job and to reduce the chance of fine edge nicks.
As Ken has said too, sacrifice a 1/4" or 1/2" off of one end and try a practice cut or two first so your real cut comes out well.
It is very satisfying to make your own gear.
Enjoy,
Tony

You can find this version at Tandy. These will work much better if you take the time to sharpen them a bit. The cutting edge often has a burr on it that will tear the leather. I would use something like this on the back side to get a nicer corner then use a plastic or bone "slicker" on the edge to round and burnish. Tandy offers a plastic slicker that looks like a wheel for a dollar or two that works wonders when rubbed briskly along the edge.
