Silky Pocket Boy 170 Purple Handle. Extra Fine Teeth.
This Extra Fine tooth blade is great for dry wood, bone and fine woodwork, all the quality you'd expect from Silky, SK5 steel, made in Japan.
Just a longer version of the 130, greater dimensions, but also great cutting ability. If you can spare the pack space go for his one, if not, go for the 130 version
I have used one of these for 6yrs and feel so familiar with it that I'm very happy to whole heartily recommend it as an essential bit of kit. The folding saws are highly effective. These Silkys are the best made, best designed and the blades are superb, these are nothing like the cheap large tooth saws, but are high quality steel combined with cutting edge design and they will last a long time and cut you alot of wood, hard dry and green. Superb tool. Folded up they go neatly into any backpack or daypack and are easily and quickly deployed.
