So I just purchased my first XM-18 from another member on the forum, and I must say, I love it. It has been used, there are a few marks and scratches (nothing major) on it and the anodize titanium is a little faded. But I think it gives the knife great character, and besides I wont be afraid to use it and put the "First blemish" on an otherwise perfect knife. When I first picked it up, I could feel the quality and superior ergonomics. I felt like, this is the knife I have been looking for since I started my journey with this hobby. I may be ready to send some of my other knives down the road to make room for another.
I did have a few questions I was hoping those in the know could answer for me. Here are my questions:
1. There is a tiny screw on the lock bar side of the knife. It can be seen in the picture below, just under the pocket clip insert. it goes about half way through the knife and does not meet the titanium on the other side and I am just not really sure why this screw is there and what its for.
2. I have a sterile blade (no hinderer logo), just CTS-XHP kind of etched in the blade. I have noticed a lot of other XM-18s out there that do not have the hinderer logo on the blade as well. I was just wondering if this meant that the blade was replaced, or refinished, or if knives made in certain years may have came that way.
3. How can I tell the approx. age of my XM-18 (What gen. knife)?
4. What is the deal with the steel types used to make the blades? So far I have seen them in XHP, S35VN and 20CV. I was wondering if all of these steels are still currently used in production or if certain years, steel types were limited runs, or if they changed over time and you steel is an indicator of when your knife was made. I was also wondering if there are other steel types, other than these 3 that are used in the XM-18 that I may not be aware of.
Thanks in advance for any info you guys can provide as I continue to grow as a Hinderer enthusiast.
