I use tool rolls for certain tools, I think it's made from Cordura or some other heavy canvas type of material. Sometimes it's convienent, other times a tool bag is more useful. For example, if you have a lot of long narrow items, and you need to have the entire selection exposed for a certain task (i.e. wrenches, screwdrivers, or in your case cooking utensils) and have plenty of space to use it, it works great.
However, it does take up a decent amount of flat space to have it unrolled, so say if you're working on a small area where there isn't a lot of area to lay it on, things tend to fall out. And sometimes the space/storage ratio isn't great if your tools aren't uniform, such as using it to store short or misshaped items. That's when I like using a small canvas toolbag, you can set it on a dashboard, shelf, your lap, almost anywhere. I use multiple smaller bags to separate my stuff into different catagories, that way I don't have to dig through a huge bag looking for one item.
I think a tool roll is better for storing items too keep them from getting damaged, but a tool bag is easier to actually work from.
