This one was commissioned by a cousin of mine as a birthday gift for his teenaged son. Our team has completed an exhaustive battery testing regiment and we would like to share our experience with your team.Teams accrue batteries over time, but which ones are good for competitions? To better understand battery performance in a competition environment, students researched and implemented four industry standards of battery test.
Very different blade styles, but basic construction is the same.
The steel is forged 5160, triple normalized, triple hardened in canola oil, and triple tempered.
The handle wraps are paracord with lemon yellow for the underlays, black stripped of its core for the overlays, and two-strand Turk's head knots of unstripped black cord, all sealed with Minwax Wood Hardener. First up is a little quasi-kwaiken that I gave to an artist who had given me a couple of flower paintings as birthday gifts for my girlfriend and mom.
She had been eyeing a couple of other quasi-Japanese blades with the Kill Bill wrap (that have yet to be seen on the Interwebz), so I made this for her. Blade length is 4 1/2" and overall length is 9 1/4".
was quite surprised and happy to get the knife, as my mom and girlfriend were to recieve the paintings.
:) Next is a primal Bowie with a blade length of 7", overall length of 12 7/8", width of 1 3/4", and spine thickenss of 7/32" at the base with a distal taper to the point.This started out as 3/4" round bar, so you can see how much it stretched out. Great work and will now have to learn another skillset ......braiding paracord for my survival knives.In spite of the large size, it's quite light in the hand. Just when I thought things were going smoothly..... The batteries were then ranked from first to worst and a strong correlation was found between not only battery age but the number of charge and discharge cycles a battery goes through.Finally, an engineering report was written so that other FIRST teams would benefit from our findings.In the 2014 competition season, our robot had a complete failure during a critical qualifying match while on the field.
