damascus (or pattern welding as I prefer to call it, since that is what it is) is a very addictive thing to make. Once you start making it and learning to develop patterns, you start to think of what to do next and pushing yourself both in design and technique. Mosaic patterns (such as the snowflakes) are getting more and more elaborate thanks to CNC waterjet cutting and powdered steels, on the most part I'm not a huge fan of the resulting patterns as they end up very busy. The addiction is normally only curbed in the skilled by lack of machinery such as various grinders, milling machines, presses and hammers.
I'm not lucky enough to have many of the toys (tools) that make pattern welding fast and economical, so I don't make a lot and stick to lower layer counts and somewhat less complicated billets. That said, I have been doing more multibar pieces because you can make small amounts of welded steel up over a long period of time and then when in the mood stick them all together into one finished piece that is far more complex than its parts.
As a maker of the stuff I love looking at other smiths pattern welded steel and trying to work out how they did it and how much material was lost through the process. There are some great bits out there, not just blades but tools, clocks, boxes, candlesticks, etc. I think its a shame that it doesn't get used for more artistic objects. Blades do get scratched, the pattern fades, etc
Mind you, my EDC pocket knife of the last 18 months has been a pattern welded blade with mokume (non-ferrous version of the same stuff) handle. It isn't as bold and clear as when new, but it still shows the pattern and looks ok. I'm going to make myself a new edc fixed blade for work soon, to replace my current one, and I'm thinking a multibar pattern welded piece with wrought iron and some gold and silver inlay, probably an inlayed or engraved handle too. Sure most would look at it and say that it isn't for using and is a purely decorative piece. Sod that! I know that the blade will be up to anything I will be doing with it and since I can have a blade like that, why not?!
Most makers will make the blades to work as good knives, its just that the buyers are unlikely to want to scratch them
