This fits my four professional chef’s knives (a 12” Twinstar, two 8” Pro series, and a rocking Santoku, as well as a filet knife and an 8” Elan bread knife. I can also place my two paring knives, my 5” serrated utility knife, and 8 of my steak knives into the block,

Added bonus space include a slot for my sharpening steel, my Henckels shears, and a cleaver that I have yet to purchase. The swivel action of the base is very smooth and responsive!

My only wish is that there were some of the thinner slots replaced with slots for additional santoku-style or chef blades - 4 is great, but 6 would have been perfect.
