Designed to Last a Lifetime
The 18 pc Executive Chef Collection is the original set that GW has been selling for years prior to our current upgrade.  The main difference between this and the 19 pc set is that this set only has the regular diamond stee and it has a 6 inch utility knife instead of the 10 inch boning knife.  So, if you do a lot of boning and filetting then the 251 might be a better choice.  If you don't need the diamond steel and prefer the 6 inch knife, then this set is for you.
