BOB T Posted March 3, 2017 Share Posted March 3, 2017 There's some pictures of my first Damascus blade, didn't have a lot of the material to make a large knife, so did what I call a "cheese knife" in the shape of a meat cleaver. The total length including the handle of 6 1/2" and the width of the blade in 1 1/2". 80 layers and twisted , the steel I used was 1084 ,1075 and 15n 20 ..Etch in black coffee . Happy how it turned out , Not sure how much knife making I will do??? I 'am not into a lot of grinding, sanding and polish.. Quote Link to comment Share on other sites More sharing options...
1776 Posted March 3, 2017 Share Posted March 3, 2017 Looks nice. Etched in black coffee? Looks like the etching turned out nice to. Why did you use black coffee? If I may ask... Quote Link to comment Share on other sites More sharing options...

If I may ask... REAL men don't take no cream and sugar on their blades! Looks good Bob, I like high contrast low layer count pattern welds. I don't know how it'll do for slicing cheese I think it'll be hard to push through. Put a wood handle on it and call it a lobster cracker? Frosty The Lucky.

BOB T Posted March 3, 2017 Author Share Posted March 3, 2017 I just used Folgers coffee to etch the blade ,no cream or sugar..lol Nothing special ,the way I drink it .I have a Keurig that I used to make the coffee . I really didn't keep track of the time I etch the blade, probably around 90 minutes there about ??? bobasaurus....The only heat I used was the hot coffee , just hot coffee from the coffee maker ,no extra heating ..All I did was clean the blade and put an wax/ oil on it.

ThomasPowers Posted March 3, 2017 Share Posted March 3, 2017 Lots of different etches for pattern welded stuff besides ferric chloride: all the mineral acids (nitric, sulfuric, HCl, etc), probably all the vegetable/fruit acids---(lime juice is a traditional etchant for the keris), tea, coffee, differential rusting,....

JHCC Posted March 3, 2017 Share Posted March 3, 2017 Fascinating information about the acids found in coffee HERE. It seems that there are almost fifty different acids in coffee, and their relative proportions and concentrations are governed by roasting time, ground size, brewing time, and brewing temperature. (No information about the etching effects of cream and sugar.) Quote Link to comment Share on other sites More sharing options...
Benton Frisse Posted March 9, 2017 Share Posted March 9, 2017 Awesome stuff about the coffee! Does it tend to be more or less aggressive than white vinegar? Beautiful slicer, man! Quote Link to comment Share on other sites More sharing options...

I started with the intention of making knives. I prefer to eat coal dust over grinding dust. Or, people with skip the grinding, and just slap on the word "rustic" or "vintage" to the end of the description and watch it sell.
