Better than imagined - solid and clean build quality and excellent sheath.
Excellent knife. Far exceeded my expectations. This is the first knife I have purchased at this price point and I am stunned at the quality.

Razor Sharp, perfectly beveled edge on the full length of the S35VN Blade
I purchased the mini version of this knife (Pentagon FX Covert) on Amazon about 4 months ago and the bevel on that blade was badly uneven/mis-sharpened and misshapen. So I was hesitant to buy the full sized version, but thought that if I received another bad "specimen", I would just return it this time. The sheath and mounting/attachment points on this knife are much better on this model than on the Covert model. Amazon also had it for about $40 less than most other online blade vendors. My issue is with the manufacturer SOG Knives, as their customer service has been completely silent and unresponsive to my attempts to contact them about their product warranty and my desire to return the Covert Model to them for resharpening.

Disappointed
The knife is well made and everything I wanted. However, the knife came dull and unable to cut paper. For the amount of money this blade cost, it should come razor sharp. SOG needs to do better quality control.

Good. But…
Good and looks great, but super dull, can’t cut anything
