I'm looking for my first proper paring knife and am considering either the 9cm (FF-PA90) or 10cm (FF-PA100) length from the Tojiro DP Damascus Series. My primary attraction to these knives are their very comfortable handles. Beyond the 1cm difference in length, the main difference between the two is the shape of the blade, the 9cm being straight. I imagine that would also make it easier to sharpen consistently. My primary usage will be with apples and pares and such. Here in Tokyo I can get either for about 6000yen so cost isn't a significant factor. Any words of advice? What do you think?
