Several months ago Crothcipt sent me a new 90mm zhen fruit carving knife http://www.chefknifedirect.com/Zhen-.../dp/B004RJ3IVS if I promised to do a review. It replaced a Shun sheep's foot paring knife that was used only for deveining shrimp and that's all I use the zhen for.
This is a tiny VG-10 knife with a extremely thin spine and rubber handle. HRC is 60-62.
I've used the zhen on several pounds of shrimp and while the Shun is a far superior parer overall, this little thing is perfect for deviening. More nimble than the Shun, the sharply tapered blade makes it easier to take out the vein. It takes a sharp edge which should last quite a while since it's never coming in contact with a cutting board.
Quick review for a simple knife. Thanks Crothcipt!
