Great Knife
This is not my most used knife. But I have it in my EDC rotation. And sometimes I just want to use this knife. It is a great cutting knife. I like single blade knives as I rarely have the need for multiple blades. I like the synthetic handles. Has a great feel to it and it is tough and you don't really worry about it like you might with a bone or stag handles knife. It is a working mans knife. And it does the work well. Big enough to do most jobs. But thin and light enough to carry easily. This pattern should be more popular than it is. Give it a try like I did and you will grow to appreciate it. I am looking to get a few more of these in my collection.

hi
Very nice, i got excessively critical a while after i got it but now that i found it again i see that it is a dang good knifeWhy that happened is that it got some crap in the pivot making it extremely gritty, seem to have disappeared, pivot smooth nowAlso, i was a bit disgruntled by the extremely thin blade, ground slightly too much as well, it is a bit diffcult to sharpen because it is so small, but i manageGet one, blade length is 2,8 inch
