I use two bags. One Ultimate Edge for my knives and one small duffle/linesman type bag for accessories. I carry a lot of knives and with spoons and stuff my Ultimate Edge was too heavy and cumbersome. It was also annoying to pack and unpack. So I added a second bag and it has been awesome. Plus I don't keep anything that expensive in it (and I work with great people that I trust) so I usually leave it at work and just take it home for my days off. It has lightened up my knife bag and made setup/breakdown much better. Here is the lineup:
2x 245mm gyuto (heavy)
150mm cleaver (heavy)
I also carry some doubles based on what is new or strikes my fancy at the time. Right now I have two 210mm pettys, 2 270mm sujis, and 2 parings. Since I have an accessory bag the third page of my UE bag has pens, sharpies, notebook, bandaids, ibuprofen, oyster knife, moribashi, measuring spoons, fish spat and some other miscellaneous stuff. Most stuff in here other than the pens & sharpies doesn't get used that much.
5 Kunz Spoons
4 Other large Spoons
3 Tasting Spoons
DMT 8k Diamond Plate
More pens & sharpies
And probably some stuff that escapes me at the moment.
I have a yanagi, deba and usuba that I use on occasion. When I bring those to work, I usually throw them in this bag as they have nice secure sayas.
Things I would add to a lineup would be a honesuki/hankotsu, slicing cleaver, 300mm suji or scimitar. I have most of these but they haven't made it in the rotation as of late, mostly to due to my daily needs, not because of the quality (or lack thereof) of these knives.
