Why would I get the 6" chef's knife when an 8" chef's knife exists? A 6" chef's knife is for someone who knows how to use their knife and is confident that it's all they need. You have a proven track record of many successful meals and dozens of satisfying dinner guests. You don't need to show off or impress anyone because everyone who's ever met you is already suitably impressed with your prowess in the kitchen.
It's a small chef's knife suitable for use in home kitchens or very tight spaces. It's a bit more versatile than a larger chef's knife. Due to its size it can also accomplish some of the same tasks as a utility or paring knife. It's easy to use off the board but has plenty of knuckle clear for on-board use.
Because it's a stainless steel you can be sure that it will hold its edge for a long time and the finish will resist corrosion and patina.
The handle is proportional to the blade and it is very comfortable for people who find the size of an eight incher intimidating.
For the record, this author reaches for the 6" chef knife the vast majority of the time in the kitchen. I cannot endorse this knife more.
