My .02 is that 5 years on an oft-used handsaw is alot of use, so a sharpening is in order regardless of the jumping problem. Get it done, and see if the problem is resolved. Because, did it always jump? Or did it just start? Good sharp and good technique, the saw guides itself and cuts without issue. I’m guessing you haven’t changed your approach.
