After nearly slicing my finger off on some Japanese plaster packaging, I thought I'd go one better and actually buy a Japanese thing that is meant to be dangerous. 

Well not exactly. You see I really like penknives. I live in Hackney so I don't carry the bigger ones I own around as I'll end up banged up like a kipper quicker than you can say knife if I ever got caught with them, but I do own quite a lot.

And this is my latest purchase. It's from SCP (www.scp.co.uk) and comes from Osaka in Japan. It's a carbon steel carpenter's knife and is stupidly sharp. It's 15cm long fully extended and not actually that specially made, but it's a super-functional piece and I can't see it falling apart for the foreseeable.

But what I really liked about it was its box. First because the illustration is not the same as the actual knife. And second because the cheap three-colour print is beautiful.

My son is learning to speak Japanese so I'll ask him what it says. If I find out I'll let you know.

And if you see a good penknife, buy it for me, I'll let you have the money when I see you.
