Ok, it's not mine I bought it for a friend for Christmas, but I wanted to review it since there are almost no Sentinel reviews and I'll post a customization when we get it done. Anywho, this has the same specs as my Prophecy V3, Adegan Silver with color discs and no sound. I didn't buy a covertec disc because he likely won't wear it like I wear mine. When I bought it I tried to anticipate the length, but in person it's bigger than I thought it would be both circumference and length. The best way I can describe it, is as a proper katana hilt, you can grasp it at the top and at the bottom as it feels fantastic. I played with the color discs since I had two of everything at this point and two blue discs and two red discs totally make a difference in color, so if you're thinking of getting Adegan Silver because of the versatility, definitely buy an extra set of color discs because you'll be able to make even more colors as described in my other review. If US management reads this I would suggest they include 2 red and 2 blue discs, but that's just my two cents for better customer satisfaction. i asked my friend what color he wanted and he told me to pick the color that best suited him, so this is what I came up with.
