  1. how can i keep rust from building up on my blades

    for oils use wd40, just dug these items from snow (freaking cold) when I saw this post.. (saw blade has been on rain for 6 months, other piece 2 months more, snow came week ago..) These were my test items for rust protection , saw blade other side is uncoated. Please see the difference. For my 'easy to rust' blades the wooden inner part of sheath seems to protect somehow the blade from rusting(!) , just remember to wipe the blade ALWAYS before sheathing.. And use the knife frequently For rust removing put the blade on vinegar for couple of hours, and rust is gone. [edit] Sorry for bad quality picture, the other test part has only couple of spots of rust, its also blacked on oil.
  2. Good find! Nice document all in one! I have successfully used electrode potential chart information to determine metals, using silver on other electrode and other is unknown,and in between is watered (sal soda, salt...) paper, then measuring voltage. (I even build small device to determine and tell the metal, will post image of it later). One problematic material to measure was aluminum (it will have oxidation layer instantly when exposed to air).
  3. Epoxy substitute

    I totally agree with you If I see some design soaked with epoxy and it still has rivets or so on, I count these as failed or lack of skills. But certainly there are many cases where modern glues are best choice in common sense, like If you design to use hidden tang. Design matters, I also want to build and do designs which could be build in any century.

    Wow I really like! True artist!
  5. Epoxy substitute

    btw. for modern quick technique I have used those glue gun glues, just whittling long chips and filling the handle hole with those (not too full), and then gently pushing heated tang to hole and move it there around so that the clue will go everywhere in there... that will hold tight... and strong... (as soon you will not reheat the blade ) f.e. I made one fish hookup that way, and even trying to bend/round hook it will last...strong bond...
  6. Epoxy substitute

    Hot sulfur has been used for filling hollow bolsters and larger areas. (Now replaced by plastics) For wood handles tight hole (burned with tang) and then totally wetting handle, hitting blade tight on it and letting the rust do the job. Also birch bark tar (tökötti)... (Dunno about fish-glue, anyone knows?) And without doubt tight fitting and riveting if possible probably combined with some of above methods. That's what came up my mind... I'm not specialist, but these I have heard/read about.

    Forgot to mention, no glue used on puukkos, just tight fitting and rivet. (Same no gluing applies to sheaths, except the wooden inner cover which is made from two parts)

    Wooden part covers the blade and at handle part there is only leather. The wooden part is for safety + gives some posture for sheath. Please attach pictures of yours when you make one! Here is small and slender fishing puukko. Handle wood part is black alder. Had trouble on handle due way too small piece of reindeer antler...

    Sheath for smaller one, added this photo so you can see the very basic shape of it. Still wet, decoration can be done at this point or later watering the skin. Stitching, string is too heavy... could be thinner.

    I made also little bit smaller version for even smaller hands (for her's little sister so she wont start to cry ) Handle length is only 3 1/4". For this I tested almost boiling candle wax (I think it is stearin), where i dipped the handle and kept couple of minutes ->After polish resulting bumpy surface on bark (which was little surprise) ... feels really nice on hand + gives really good grip. Materials and type are same as in puukko above.

    Sheath. Needs still second darker wax to give more contrast. Clip and how it's meant to be used. Easy to remove, no accident drops.

    Arvooppa and thanks. Here is one which I made on some course years ago ... not very happy about sheath ornamentation.. this is what you get when you work during hangover... Handle is riveted from top end, metal parts are nickel silver and the rest is birch bark, etching on blade. Also sheath metal parts are nickel silver.

    Hi and thanks! I made this for 13 yr. scout girl, so it's meant to be 'no so serious', tried to make this pretty Usually I like to leave some unfinished surface, so knife has really feeling that it's hand made and personal. (Earlier I grind and polished all sides and made the blade like manufactured on some factory, and every time I felt sad about loosing nice textures and the feeling of hand made, so I decided to leave something there) Yes you get good grip from birch bark handle, its little soft and it feels nice and warm on hand like cork handles on some fishing rods, except its much more durable. In image you can see the spine, on background is the hollow rough wooden inner cover for sheath (I don't know is there individual English word for it), It's for avoiding injuries if you fell bad with the knife dangling on your waist. Sorry for bad image quality (taken on web cam) and late answer, I have been pretty busy lately. I'll post the sheath image as I get time to make on. And some other knifes.

    Please can you clarify?
  15. Show me your Forge

    No, this works little different. There will form bed of charcoal under and at sides and top are coaling woods, so there is then nice "nest' for your workpiece. Enough heat for smaller needs like knifes etc. You can even burn you steel with this using only wood (Done ). If I need to run this with more energy for bigger stuff, I use charcoal / coal / wood mixture.
