I like to use my MAC Dg1000 (a Blue Point YA1000 is the same thing) hose cutter for average sized hoses and tubing. I like how the blade tip pokes into the hose and then cuts it smoothly instead of pinching the hose flat and then cutting through it all at once like most other hose cutters. Made in Canada, and the entire body is black crinkle painted aluminum instead of plastic. The blade can be removed (two small allen head grub screws hold it in) and resharpened by hand as needed. I'm not sure if replacement blades are still available or not, but I haven't needed to replace my blade yet. Don't cut metal reinforced hose with it and it will last many years with only occasional hand sharpening. This tool is strictly a hose/tubing cutter though. Due to the way the blade drops into a recessed channel when the jaws are closed, it often won't fully cut small diameter or finely stranded things like rope, twine, or vacuum tubing. Ebay is often a good place to find one at a good price, because they aren't made anymore. It seems like almost everyone flipped over Taiwan made clones or all-plastic Chinese made versions of the same style tool 5-10 years ago. They might still work well, but I don't have experience with any of them. It does look like the Lisle plastic bodied hose cutter posted by Mohawk Dave is US made.
As mentioned already, a Craftsman Handi-Cut (mine has a 2.5" blade) style cutter is also a great option and is really the most useful tool option overall. They are made in China now, so I can't speak to the quality of the current manifestation, but I use my older USA made one for pretty much any job that can be hard to do well with a utility knife or scissors. Cutting paracord, rope, aquarium style vinyl airline tubing, twine, nylon ratchet straps, vacuum tubing, refrigerator ice maker tubing, small pieces of wood or dowel, fabric reinforced v-belts, compressed air hose lines, carpet tack strips, garden hoses, etc. It cuts it all very well as long as you have a sharp blade and an anvil in good condition. If I didn't have my MAC DG1000 hose cutter I would probably use my Handi-Cut to for things like compressed air hoses and garden hoses as well. If you don't cut anything metal with it, one Handi-Cut blade will last you hundreds of cuts (and replacements are pretty easy to find), but if you want to be able to cut larger things like radiator hoses you might want to get the 4" blade version instead.
