  1. Cool profile of the blade but the tang is a bit big. Great job hammering that beast into shape .
  2. Not a false edge but sharp on both ends. I dont really plan just go with the tide. File work is all needle files, always before ht and the small grooves are traces of the old file. I tempered the blade for two hours at ~210 Cº as usual and then I submerge the edge in water for the final temper with the torch , no harm is done and blade is stronger. The purpose of the grooves is to aid grip nothing more, the polished varnish is a bit slippery when wet .
  3. I've been so busy since last year with new job and other experiments that I didnt took take time posting anything so here it goes... In September 2018 i went to a cutlery expo in Caldas da Rainha, bought a billet of pattern welded steel from Russian knifemaker Kirilov. Forged into shape, handle of brazil wood, cherry wood and mosaic pins. It's a joy working with damascus, it was easy to heat treat and the blade is quite hard and though. Secound one is forged spring steel, chery wood, pine, mosaic and alluminium pins. Made it for choping and wood working. Third one is a choper from file steel, dual temper and S file work . Alluminum guard, brazil wood, leather spacer and oak. That small thing with teeth is a broach for hidden tangs, 4mm thick at the end by 12cm long. A very usefull tool I should've made years ago. Tell me what you think..
  4. Didnt knew such a file existed, gonna get me one of those! Keep the good work!
  5. Excelent fit-finish and choice of materials !
  6. My latest tool. After a lot of research looking for the most efficient design, went ahead with the ribbon burner forge. Used the same forge container (old safe) that I used for 2 years on charcoal. 4cm thick refractory bricks on the walls, 2cm on top and hight temp silicone to fill the gaps. I had empty oxygen bottles from my oxy torch, with 73mm in diameter, those became the ai/fuel duct. Welded a 1/2" steel bushing and a cap with 5mm whole for the gas outlet. All aluminium butterfly valve, ol' lady hairdryer, high pressure regulator with manometer and 24 lb/11 kg propane tank . I'm very satisfied with this forge, it is easy to light, easy to control the heat for forging or HT and there´s little maintnence involved. I'ts amazing how well this thing works, better than I expected... Black snout, smoke smelling clouthes, burnt metal and mess allover the floor are a thing of the past. Goodbye charcoal!!

    Third Dagger

    My initial plan was to do the plunge lines only on the belt grinder, for a smoother transition into the bevel. Not pleased with it because I know I can do much better with just a file. It's the only thing i dont like about this knife. Thanks for the feedback.

    Third Dagger

    Daggers are becoming my favorite type of knive, simple yet difficult to get right. Spring steel blade: 16cm Copper guard and pommel Handle made from oak, palo santo and aluminium. Through tang construction and peened at the end. Leather sheath engraved with weave. Always a pleasure to share my work and critics are always welcome. Cheers

    It's only fair.

    I cant see anything to criticize, All that remains to know is how they perform .. Next step is make a sheat for those two.
  10. "that's a knoife"... Mighty blade, I would put a smoother transition beetween the guard handle, handle seems a bit blocky and outcast from the perfect fit & finish blade and guard. Nicely done.
  11. For wood crafting it's best a scandi or full flat grind .
  12. Why not a medieval crossbow. I built one years before I got into knife making.
  13. Yes, the top finger groove is for the thumb, it gives more grip for thrusting. None of these were forged, just true up the steel on the anvil and straight to grinding. Thanks
  14. Small details make a big difference, the bolsters are my favorite. Well done.
  15. New work The bigger one is a further development of a design I started in december 2017, made from spring steel with paulo santo and cedar wood, edge quenched and tempered 1 hour around 210 cº. Spent three hours just fitting the mortises, it's the most difficult part of this knive and I havent figured out how fit them perfectly without epoxy... yet. Did a bit of choping and it kept an edge really well. The other is a stainless X48 ( 440a equivalent) blade with aluminium guard, paulo santo and blood wood for the handle . HT is done by heating to 1040 cº and air cooling temper around 180 cº, I dont have fancy Ht oven so I quenched in veg oil after reaching vivid yellow and tempered twice for 30 mins to straw color in the oven. I've used this methods few time before and they work just gotta test the blade for flexibility because this steel wont hardened like simple high carbon does. I've also got new leather stamps and went with a basket weave effect on the small sheath. Cheers
