Here is what I use for mine. I use all three of those. The far right is to cut pieces out and they are tiny enough to do so if you need.
I also have purchased some smaller unfinished wooden dowels which have helped greatly with shaping pieces like when it comes down to rounding out some them. Get a few different sizes because you never know what may actually help, plus I've broken a few too.
I also use an anti-static mat that I normally work on computers with but it comes in handy to seeing all the pieces and keeping everything close.
Hope this helps!
