I don't know whether it already was a theme but what's about health hazard when inhaling air through heated aluminium. Could it be a problem? The pure handle is looking very uncomfortably and not pretty nice. Did anybody try to make a wrap out of leather or paracord for it? I would do so if I would have a Sup 3 (VAS is growing!). There are a lot of nice possibilities and the handle will afterwards lie much better in your hand. Look for 'paracord' and 'wrap' at youtube. Many nice designs. Make your own "Supreme Katana"
