The Real Steel H6-S1 is a high quality, high value folder. It has a solid frame lock and uses sound materials. Real Steel has rounded all the critical edges and it feels good in the hand. This would be a good choice for someone looking for an EDC blade. The materials in this model do show scratches fairly easily and the size a bit larger than I find ideal in that role, but you can find out more info on it HERE.
This knife pictured here I purchased second hand, and it appears to have been well modified at some point. The thumb stud has been removed to make it a two-handed opening knife. I am not allowed a one handed opener where I live, so it fits my locale well. One can see that a plug has been installed where the stud should be.
