    SOG Pentagon...

    Posted by Peter Sirangelo on Nov 17th 2023

    First let me tell you that EKnives is awesome. ANY time I have ever had an issue, they quickly took care of it, and if there was a delay in response, they even apologized for it. Now the knife. I read reviews on it after I purchased it. All the negative reviews are correct, the blade rubs on the way in and out, and it misfires both opening and closing enough that I would not trust it for anything, also at times I needed to use two hands to retract the blade. I sprayed it with Rem oil first, and that didn't help, then on suggestion from EKnives I used WD-40, and It made no difference . The blade was sharp, except for where it rubbed, the blade has next to zero movement/rattle in the open and closed positions, not something many OTF manufacturers can claim. Was very ergonomic in hand, and the side switch was big, and comfortable. It's a shame and no fault of EKnives, and to their credit are helping me out with this. If SOG fixes their bugs with it, I would gladly purchase another one. Except for the rubbing and reliability issue I really liked the blade. Maybe in the future. I give one star solely based on SOG and not EKnives. If there was a separate area for them, I'd give them five stars, but the knife has issues that I believe stem from design issues or manufacturing issues or materials.
