I have 3 TOPS knives including the Scalpel. I picked it up because it looked like a neat knife and I liked the concept (or maybe it was the name... it sounds like a good cutter!). For a blade that small the spine is thick. I spent a bit of time on the Sharpmaker trying to but a finer edge on the blade but with the thick spine and short height it was rough. Overall, I have not used it that much. At that size it is easier to just use a pocket knife.
I also own the Lone Falcone and the Steel Eagle (Hunter's point). Very nice designs (both are keepers, Lone Falcone has seen moderate use). But again, with the Lone Falcone I had to spend a lot of time with the Sharpmaker to make edge cut-worthy!
