This is some my work
#1 2 steel flashlight and laser(304 steel)
#2 is my steel-brass mix host-cyan color
#3 is titannium-copper mix host
#4 is moster mix steel-brass-copper heatsink
#6 is my pen laser 638nm
The mix copper and titanium host is absolutely stunning, i am not even sure if there are words in the English language that can describe how badly i want to buy it but alas, being a student, i'm no where close to being able to afford it. Perhaps i would bite the bullet a couple months down the road.
