Review: Great quality - Durable material. Weight is nice. Sharp blade. Works well. Design is nice. Has held up pretty good
Review: Feature Rich & Great Price - The skull artwork design was beautifully done...especially in green. I'm certain the blade material is not a high-end steel, but the knife is an exceptional value providing you with a decent blade, rope cutting capability, glass breaker, spring assist opening, and a belt clip all wrapped up in a cool graphic (if you like skulls). The overall weight of the knife felt lighter than I expected, but was balanced in the open position and felt good in hand. Makes a great gift. Artwork wore off from being in pocket after a year. :(

## Questions & Answers

**Q: Can you widdle with it**
A: It's not designed for whittling nor is it the world's strongest knife since it's a "folder".  But it IS VERY sharp, opens in a flash, and could be used in an emergency to break a side window or cut a seat belt.For the price, it's GREAT!

**Q: Does the blade lock?**
A: It locks open but no lock to keep it closed but didn't open in ur pocket

**Q: What kind of screw does it have.**
A: I believe they are called Torx bits, not sure what size, but it is not a standard phillips or flat blade. You can get a Torx bit set in the range of sizes that would include the size for the knife's range at any auto supply store, Home Depot, or Hardware store.

**Q: How much is shipping?**
A: mine was free, but i am a Prime member

### ⭐⭐⭐⭐⭐ It’s great for the price
*by D***N on August 10, 2024*

I got a handful of Master USA knives 7 years ago all together for $20. Pretty good deal for amateur knife collector. They’re good knock around knives( not to get tore up if you lose them, roll the edge, chink the blade or if the corrugated scales break). Good enough for utility if you maintain the factory edge but if you want a scalpel edge then it’s a five stroke, resharpen kind of blade. I wouldn’t bet my life on them but if I had to I’d roll the dice in a survival situation. This is an instance where you get what you pay for but for less than $10 there’s not a lot to argue
