My first homemade knife is nearing completion so until its done i will just tell you about it. Its big, made of d2 file, double wrapped and epoxy coated handle. So you can see the wrap.. it is sharp as i learned and relearned a couple times dont sharpen it til he end....holds an edge really well and is easy to sharpen using a diamond stone. I chose a convex edge with little lead in because it will be my hard use blade. Hope it will be done this week. I still need to add two turks heads on he ends of the grip since i used no brass or such to keep your fingers off it. The profile is modeled from a SOG government agent but with more curve near the tip for skimming.

From a machinist i work with. I got two of them. I will ask him how sure he is about the metal but he claimed d2 pretty adamently. Our shop used to produce many specialty items that required unique tools. That much i know. He also has rockwell files to check he hardness of items needed to be made or repaired. Until i know different i have to defer to what i was told. I do know these two files out performed any other file i have as far as cutting goes. We also are able to temper here though we were very careful about keeping the heat down.

Not doubting you on the files - just never seen one made of D2. But then again - I lead a very sheltered life.

I spoke with our machinist and he says it may be d2 he thinks it was one of an order for a project years ago. We are doing some record searching to detrmine if this is one of those. He also said its not o1 and whem we get a chance we will rockwell test it. Let u know what we find out.

Ok no word yet on the research (purchasing files) on the origin of the file used, but I have a problem with my epoxy. The first I bought didnt dry fast enough and ran in spite of me spinning it to keep it evened out, but even though its the same brand and type, this new batch is drying so fast its not flowing enough and not letting it soak into the paracord. I may have to do it again from scratch cause you cannot see the turks head knot and lanyard. I can file and sand the epoxy but once down can it be polished with a buffing wheel? Should I just wrap it and dip it in resin instead like a modified crashcarta? HELP!
i REALLY like the idea of being able to see the decorative wraps on the original epoxy set but this second batch has me confused.

I don't use epoxy for my wraps, but rather fiberglass resin. After the resin cures it can be sanded and buffed.

Sorry man, I just saw this. Epoxy resin can be sanded down smooth and buffed or polished to a glossy shine. It needs to be fully cured. The first thing you want to do is wipe it down thoroughly with acetone to remove the stickyness on the surface. Then you can sand it to a uniform surface with coarse and then continuing finer sandpaper. This will go faster if you can wet sand it using wet or dry sandpaper.
Epoxies can be difficult to work with since they have to be measured VERY accurately and mixed VERY thoroughly as well. I always recommend mixing by stirring well making sure to scrape the sides and bottom of the mixing cup and then pour the epoxy into another cup and mix it completely again! I know that sounds sort of silly but epoxies are just that sensitive to make sure everything is so so. I have dispenser pumps that are precalibrated to measure out the proper ration of hardener and resin.
Hope this helps, if you have any other questions please ask.

I used a premeasured dispenser. but I am stripping the epoxy off and giving crashcarta a try. I have an idea of what it should look like and since it don't and I haave to start over anyway what the hell.

Are you going to use Polyester Fiberglass Resin this time? Some epoxies are hard to get to soak through some fabrics since the liquid is so thick. |
