I ship mine. I was using the cardboard box that Big Blue's blades came in, but this means I had to ship the bandsaw blades separate from the TS, SCMS, Festool and the metal cutting saw blades, cost me $15 to $20 more, so I made a box.............
Here you see it all, there are six blades to ship, I think I can put another two round blades in there, if I had to.
The round blades stack one on top of each other, there is a thick washer between each blade to keep any sharp bits from touching each other, then a long bolt with a knob on it holds them all in place.
Next the bandsaw blade goes in the box, this is held up off the stack of round blades by some spacer blocks. The bandsaw blade is also held in place by some blocks on the one side of it, and to ease removing the blade, it is restrained by two large twist ties.
Next is a bar that holds the bandsaw blade in place, it has two cut off nails in one end that go into two holes in the side of the box, then the heads of those nails go into slots in the other side of the box, this stops the bar from moving around, as the final screw goes through the lid and the bar into a threaded insert nut in the large block of wood there.
Here the lid is slid into place, and secured with a large screw.
Finally the bottom of the box, you and see the "T" nut that the long bolt securing the round blades threads into.
I'll shoot a coat of poly on it, just so it says somewhat clean looking, and it will be on it's way
The whole deal comes out to just under the 120 cm size (they measure height, width and depth to get the size) so I can ship all the blades for about $12.
Here, in Japan, finding a sharpening service is not easy, the one that I found that I could drop stuff off at did a really lousy job, so I did not want to go back there, but the guy that I ship to now, he was recommended by the Tenryu blade company, and he has done a very good job, and his turn around was a day or two, not bad.
So how to you send in your blades?
