I Have Been Looking At A Skinner Knife Made By Frost Cutlery. Just Wondering If This Brand Knife Is Decent?

I have never heard of them before, but it looks to be well made.

How Do You Clean Stainless Steel Cutlery That Has Been Tarnished From Silver Cutlery?

Soak cutlery in dilute vinegar, rinse with water.
Then wash with neutral dishwashing liquid.
