Dear Colonial Knife,                             

I was looking around a Coast Guard Facebook post the other day and saw a reference to the COLONIAL KNIFE USN RIGGER’S knife. As a young kid in the CG, I used my 1757 Marlin Spike continually doing all sorts of jobs the duty officer assigned to me and I had forgotten about that knife and the Marlin Spike, until now, so I purchased the 1757 Marlin Spike. It arrived today! Wow, it sure brings back memories. It looks to be a very high-quality knife for the money, and one I am sure I will use well.

Many Thanks! Craig M. Seattle, WA. retired Coast Guard

Review:

“Hello, My name is Mark Grinder from Arkansas and I am an industrial electrician. I received the marlin spike a birthday gift and I love it! I use the knives I collect and this one is my 1st choice. It’s got a big handle so your hand doesn’t cramp up. A thick blade that takes everything I throw at it and the marlin spike is the best part. I do some rigging at work and rope work as a pastime. The spike has it covered! It also acts as an awl, I clear bolt threads with it, I pry with it and even align equipment bolt patterns. One word for this knife-INDISPENSABLE!”
