I bought a new Blanchard 10cm plough gauge and find it pushes the strap so hard against the guide that it takes a great effort to cut 8-10 oz veg tan. This is most noticeable with narrow straps, 1 inch or less. The strap has a tendency to ride up on the guide to relieve the pressure as it exits the blade. I understand that the one sided bevel on the knife is designed to keep the strap against the guide but it seems excessive. I sharpened and honed the blade and it is quite sharp by my standards. It easily slices through 12 oz HO veg tan when using the knife freehand without the plough gauge. The bevel on the new knife was a bit rounded and I worked on flattening the bevel (20-25 deg. taper) as well as the flat backside, finishing with a 4000 grit waterstone and stropping. This didn't relieve the pressure. Next I tried shimming the blade a slight amount, moving the point away from the guide. No improvement. Finally, I put a tiny (barely visible) taper on the backside of the blade edge. No change. I'd appreciate suggestions about sharpening and using a plough gauge. Previously I've had good results using a draw gauge and a wooden strap cutter. I bought the plough gauge to cut wider straps consistently, although most of my strap work is in the 3/8 to 1-1/4 inch widths.

I want to start out and say I have little to knowledge of plough gauges and no experience with them at all. But I do have the chance to pick one up from a local guy who got some tools from a friend. Looking at the plough guage, both sides of the blade are beveled, and correct me if I'm wrong, but from my understanding only one side should be beveled. Does having both sides beveled ruin the blade? Is it fixable? If so, how intensive would that be? They were asking like $200 for it, if that is a defective blade, is it even worth it anymore, if it still a good tool would it lower the price? Looking forward to learning about plough guages here.

I bought this German Plough Gauge on a Norwegian auction site for 37$, when I received it today I could see it was a complete bargain. The lady who sold it had other tools for sale too, however they where all priced to "regular" used tool prices. It is a very well made tool, I had to sharpen up the knife because it had never been used/sharpened before. I did some research and found out it is made by M. Paffrath OH in Remsheid, Germany. The German company also make other leather tools like pliers and punches http://www.paffrath-remscheid.de/index_eng.html . The new price of this tool is more than 300 Euro, I almost feel bad about buying it that cheap. She obviously have not paid that much for it herself. I do not know the story behind it, perhaps she selling the tools for somebody who has past away; all other tools was priced correctly to what they was worth. This plough has an unusual attachment, some kind of material wedge that goes in a slot to the right of the blade. The purpose is either to reduce knife drag or to compress the leather against the material guide. It did not work at all with firm leather, perhaps it is intended for use on soft leather I do not know. Also the knife is set up in an inside angle against the material fence, I do not know if it is made like this intensionally or by mistake. German tool makers seldom makes mistakes, and it cuts leather very well. The knife is exactly like a Blanchard knife and fit their plough as well. I do not like the guides locking screw, it makes the tool look cheap. They should have been using something better than this thin screw, it was also bent when I got it. A other detail i do not like is how the knife is attached, it might be practical but look cheap compared to the other tools. It is clearly inspired by the Blanchard tool, with some improvements it could have been a alternative to it too. This tool is not molded in one piece of brass like the Blanchard is, the ruler and the knife base is made in two parts that is either glued or soldered together. All parts on this tool looks like they are made in a CNC machine, on a Blanchard plough all parts are molded. The German tool is all solid brass an weight 875 grams, when the Blanchard is made lighter. I do believe lighter is better, when these tools mostly is lifted by their knife handles. This reduce the risk of the knife blade to break off in the attachment slot, as they used to do with the older tools heavier frame. The knifes look the same, however the Blanchard has thicker steel. A 15 cm Blanchard plough with one blade costs 319 Euro before tax and this one costs 245. Still I would rate the Blanchard as a better tool for the money. I attach pictures of the tool with and without the wedge. Compared to a 10 cm. Blanchard and compared to a 15 cm Mayer Flamery of the older French pattern. Not much has happened in hundred years, old is still the best. I am interested in knowledge or opinions about the wedge and the tool in general. In advance thanks. Tor
