I use my pocketknife daily from multiple uses and I always keep it sharp. But, I find myself carrying my putty knife almost daily, as well. Somethings I just don't like dulling my blade for. I use my putty knife for scraping splattered concrete off of the concrete floors, scraping drywall mud off the floor, etc. My Hyde putty knife is cheap in comparison to my knife. I like to keep it sharp since sometimes I'm scraping stickers off glass or painted surfaces.
