Recently acquired a very nice knife, the Scrapyard Dogfather.

Compared to other large knives I've used, the performance is impressive. The thick spine and saber grind are what I prefer in a knife like this, because the geometry of the entire blade rarely comes into play considering what I use the knife on. The extra weight means more power behind a chop.

The Res C handle is very comfortable and helps absorb shock during a chop. Some of the better ergonomics out of any fixed blade I've used, though the balance is forward heavy when using the choil for finer cutting due to the blade length. Not much of an issue since I usually have my Mud Puppy or a SAK for things like making fuzz sticks and slicing sausages.

The blade steel has worked very well. When reprofiling it wasn't too difficult to grind, but felt harder and more wear resistant than something like 1095. It takes a killer edge, and holds it. For example today I used the knife to take back some shrubs on the edge of my driveway. The knife started out with a hair popping edge, and after about 40 minutes of hacking of plants and thin branches the knife would still cleanly shave. I've also hit rocks on accident a few times and the edge took minimal damage, small rolls that sharpened out on a sharpmaker medium rod in under a minute. The chopping performance is very high with the new edge. With the factory edge (about 22-25 degrees per side) 1 inch to 1.5 inch branches could be cut in a single chop. With the new edge 2 inch thick branches can be lopped off in one swing. Much fun.

Even with the thicker factory edge, the knife is still an efficient trail clearing tool. This is a before and after shot, after swinging the Dogfather around for a little under 5 minutes.

The reprofiled edge has stood up to heavier chopping than what you see here, and a lot of trail clearing. Takes a very fine, hair popping edge as well.

he factory edge was tested for sharpness by push cutting light thread on a scale. The edge scored an average of 57.38, which is just above the best scores from Spyderco and Kershaw for their small pocket knives. The edge would easily pop arm hairs but did not have the ability to whittle hairs.

Initial impressions of the Scrapyard Dogfather are very positive. The comfortable handle works better for chopping than exposed tang styles, the steel has shown excellent performance and the overall design is very robust and capable.

Thanks for another outstanding review...now I want a DF even more! :D At what angle did you reprofile the edge? I've been thinking about reprofiling my Battle Rat for some time now, but I'm not sure how thin the edge should be.

Thanks in advance!
 
What did you you use to reprofile the edge, if you don't mind me asking? I've got a Scrapper6 that had the worst edge I've ever seen when I got it from the factory (>60degs). When I emailed Scrapyard they said they've quit drinking while sharpening knives (nice excuse :)) Anyway, I've been trying to reprofile it for months, but all I've got is a strop and a Sharpmaker. Any suggestions?
 
Buy some low grit sandpaper and tape it to a mousepad and you can get a nice convex profile, which is what I did.
 
That sounds like a great improvement! How long did it take you to get it like this?

I spent about an hour getting the profile where I wanted it, then a few more minutes polishing it up then honing the edge. I'll take some better photos sometime, where the sandpaper rubbed off the gray coating makes it hard to see the edge bevel in the photo I posted.

The thin edge makes a big difference, highly recommended if you get one of these and make it a user. Mine is used mostly for busting up wood for fires and making tools and clearing rail. The thin edge does a better job of biting into wood, and cleanly slicing vegetation on a swing rather than bending or breaking it like the thicker edge would sometimes do (especially if it wasn't at optimal sharpness).
 
I just find it odd that we have to spend over $200 on a knife and then regrind the edge to make it cut better...

Surely it should cut well right out of the box?

They grind the edges thick because the Dogfather is so massive it's designed as a chopper and not a slicer. Thick edges mean great edge strength.

If you read the original post, Vivi stated he had no problem with the factory edge. If you are familiar with Vivi's style, he likes thinning his edges.
 
yeah edge thickness is user choice... and the maker can't add any after it's taken off!
 
The factory edge, while thick, came evenly ground and hair popping sharp. The knife still has good chopping ability with the thick edge, like in the photo where it went through an inch thick branch easily.

I run my edges thinner than most. Every knife I've bought, from 5$ to 200$+ I had to reprofile to get where I want. In that sense I could say every 200$ knife I have has been a let down, but most people aren't as OCD about edge angles as I am.

For me the money went towards a comfortable handle, excellent blade steel and a great warranty.
 
I'm pleased to hear that. Been wanting one of those DFs for a long time but I dont have the equipment or patience to reprofile an edge.

I have a Dumpster Mutt LE and I was able to a pretty good edge on it with my Sharpmaker. Its kinda thick but I figured that was about right for a hard working knife.

Nice review and nice re-profile job. :thumbup: Bring that to our GTG next month.

Thanks, I plan to bring it with me :D

Here's some more photos and a video I put together



Some trees fell across one of the main trails, so naturally I had to use my Dogfather on them.

Used the log I chopped to make a bench, then threw up a tarp to block some of the sun and wind. After building a fire and chopping around some we rested and ate some kiwi and sandwiches and drank pine needle tea.

Saw a standing dead tree that we took down for convenient firewood.

Fun day. Working on uploading a video too.

Do you find the choil useful? I wonder if the knife wouldnt be better if the edge came all the way down to the bottom. Any idea what hardness SYK runs their SR77?
