Depends on level of commitment and results you need. To do it once and for all buy belt sharpener - Work Sharp with Blade Grinder Attachment being probably the best price vs quality vs functionality. For quality sharpening that requires a bit of time buy rolling knife sharpener. For quality sharpening which is fast and anyone can do buy electrical ChefMate with two slots and follow the instructions. PS Do not bother with anything that requires clamping the knife, etc. You’ll use it once - it’s just too much hustle to setup and adjust these systems. You spend most of the time unpacking, bolting it together and then readjusting the knife instead of sharpening. This is why rolling sharpeners work really well - fast magnetic attachment, angles are pre-set.
