I was unhappy with the quality of the knife. I didn't receive the part labeled H. Pipe sleeve. The part labeled C. Pipe reamer is more of a dab tool. It doesn't fit to ream the pipe. Some parts swing open with ease. While other parts don't open up without the use of some force. Be careful not to break a finger nail trying to use. Almost needed pliers or another tool just to use it.

The hk is poorly constructed but I sent an email and they fixed the issue in no time. great shipping fast customer service I can say I would recommend 420 science to anyone

This is a very versatile tool for all smokers So far I have used five of the twelve tools on the knife.. It comes in so handy I'm going to buy another one and keep it in my car. I'm glad I brought it!

I bought this knife as a gift and the person who got it loved it! Shipping was very fast as well! I will definitely be purchasing more items in the near future!
