Cutting hard objects with a knife, hitting the blade against hard objects, or dropping the knife can cause the blade to chip.
Small chips may not be a major concern, but if there are multiple chips, the sharpness of the blade will significantly decrease.
Small chips can be repaired at home, so I will introduce how to repair a chipped knife.
The necessary tools are a whetstone. A coarse whetstone (#200–#400) is ideal, but a medium whetstone (#1000) can also be used.
With a medium whetstone, the grinding power is lower than with a coarse whetstone, so it takes more time.
1. Sharpen the entire blade at a higher angle than usual.
Instead of sharpening only the chipped part of the blade, sharpen the entire blade as you would normally. Sharpen at a higher angle than usual. Sharpening at a higher angle will remove the chip more quickly.
2. Sharpen the front and back of the knife evenly until the chip is gone.
Sharpen the front and back evenly until the chip is gone.
3. Once the chipped area is gone, switch to regular knife sharpening to create a new edge.
Once you confirm that the chipped area is gone, switch to regular knife sharpening to create a new edge and complete the process.
By the way, washing knives in a dishwasher can cause them to chip if they collide with dishes.
Chipped areas on knives can occur even with careful use, so be sure to check for any chipped areas when storing your knives.
