I've been regularly breaking down whole salmon at work recently and the 165mm FuRinKaZan deba I bought for the task feels a bit undersized. I'm thinking about trying out something bigger, but I'm unsure on what size to get. The natural size up seems to be 180mm, but 1.5cm doesn't seem like much of a difference and I don't want to go out and buy a 180 just to find out I really wanted something like a 195 or 210. Conversely, a 210 deba seems absolutely massive. For those of you who break down lots of larger fish, does a 180 do the job sufficiently or do you like the extra length of something longer?
