Factors leading to knife dullness
Here are some of the most common reasons why your kitchen, pocket or hunting knife might be dull.
If you continuously throw your sharp knives to your drawer with other silverware and utensils, its delicate, sharp edges take a hit and gradually become dull. It is also not safe for your fingers. For proper storage, get a knife block, under-cabinet knife storage, or knife storage roll cases.
If you put your knives in the dishwasher with other dishes, their edges will bang against the utensils resulting in scratches, chips, and dullness.
The best way to wash a knife is by use of hands with warm soapy water and clean water. Before storage, ensure you dry them with a cloth as air drying is also not recommended.
A hard cutting board
If your cutting board is made of glass or granite, it damages your knives’ edges with every cut. The harder the cutting surface is, the more it affects the knife’s blade every time they come into contact. Go for softwood cutting boards for a long-lasting sharp knife.
Weak knife blade steel
If your knife’s blade steel is weak, it will not hold up well to the riff raffs of cutting in the kitchen or outdoors and will, therefore, become dull quickly. Ensure you buy knives with blade steels that show strength and toughness to avoid chipping, cracks, and total failure.
You don’t sharpen regularly
Yes! Maybe it’s dull because you don’t have regular time for sharpening. After all, however, tough, no knife will remain sharp forever.
This depends on how frequently and for what purpose you use your knives. You can sharpen whenever they get dull or lose the razor-sharp fine cutting edge. Ensure you follow the sharpening instructions from the manufacturer.
