We do occasionally get people asking this at my work, and yes it is uneconomical nowadays. The quality of saws used to be a lot better but people just buy on price nowadays.
You CAN still get saws made using the highest quality steel, with oiled hardwood handles which you could sharpen many times, with copper riveted construction. There is a hand tool shop in Bakewell which brought tears to my eyes when I went in. They sold all the best quality stuff, handsaws for £90, a wall full of plastering trowels ranging up to £80. It was heaven!! Go there if you are in the area (good riding too). They had sets of Allen keys which made Park tools look like toddlers toys, how about £65 for a set? Amazing.
