Been reading on forums, watching youtube etc. and I see a pattern - or at least think I do. As some women would say: the longer/bigger the better
I have seen youtube movies with people using knifes which they could not handle what so ever ... 260, 270 +++. I have read statements where people call 210 a girly knife and so on.
For years I played golf. The testosterone level were kind of the same. Many needed a huge driver and aimed to hit the ball 400 yards ... if they pulled it off they would tell everybody on the course. Funny thing was that they forgot to tell that they missed the 2 feet put on the same hole
I use knifes that will fit the task I'm doing. Could be a 120 petty for prepwork like mushrooms, a 180 for chopping cucumbers, carrots etc, a 210 as an alrounder and so on. Yes I have a 260 but this is in my knifeblock most of the time to be honest.
As I see it smaller knifes gives more control, better results, saves time and are a joy to use, especially when you handle a knife 100's of times on a 12 hour shift.
I will admit that I made a custom order for a 240. Was told this would be a great size for me (usually I'm using 210-220 girly size). I trust the advice I got and I'm sure the 240 will come in handy. Might be akward in the beginning but again ... I can practice 160 hours a month so I will be comfy in a short period of time.
Does size really matter? Well I will let others decide
