Is it normal to have so much spark in grinding the edge?
"Normal" if you are doing high speed dry grinding of the finished blade. If you are finishing the edge this way, you are creating small areas that have been heated enough that sparks are generated and the hardness of the edge compromised. this is what leads to user reports that the blade never took a good edge until the third or fourth sharpening. Ideally when finishing the blade, you want to wet grind at lower belt speed. so now the compromise. wet grinding needs a more expensive machine and takes more time, which means higher costs to produce.]]> oldsailorsknives When you can't have a lightsabre Fri, 24 Nov 2017 14:31:59 +0000 https://oldforum.beyondt01micron.com/read.php?20,65049,69088#msg-69088 Re: Apostle P/Bark River Collaboration https://oldforum.beyondt01micron.com/read.php?20,65049,69088#msg-69088

Different steels spark different amounts, some throw a lot :

Thanks for the info, learned something.

Btw, had been more and more successful with freehand, especially plateau sharpening. You are the best.]]> vigiloconfido When you can't have a lightsabre Fri, 24 Nov 2017 02:19:25 +0000 https://oldforum.beyondt01micron.com/read.php?20,65049,69072#msg-69072 Re: Apostle P/Bark River Collaboration https://oldforum.beyondt01micron.com/read.php?20,65049,69072#msg-69072
