These are 3 knives that I recently acquired via eBay auctions. All 3 knives are titanium alloy and the bottom knife is carbon fiber and titanium. All 3 are frame locks. The blade steel for all 3 is D2. Ceramic ball bearings aid in the rapid deployment with the flick of a finger.

These are Chinese knives bearing the name "Two Sun" etched on the blade. Each of these knives came with perfectly centered razor sharp edges. The fit and finish is top notch on the lot of them. I have scrutinized each one with a jewelers loupe and a magnifying glass. I couldn't find even the slightest hint of a scratch or a blemish.

Conclusion: Amazing, quality knives at a price point is too good to be true...but it is!
