    integral bolster pattern-welded chef knife

    Excelent fit-finish and choice of materials !
  3. 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.

    "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.

    Is this a decent design?

    For wood crafting it's best a scandi or full flat grind .

    Why not a medieval crossbow. I built one years before I got into knife making.

    April's latest mount knives

    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

    The Ghost Dog

    Small details make a big difference, the bolsters are my favorite. Well done.
  12. 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

    Finn's SPECTACULAR first sword

    That's awsome... but will it kill?

    Knife making video questions

    It's high carbon steel judging by the number of springs on the sparks, it wasnt heat treated nor did he bothered sharpening. A knife without HT is only a paper wheight.

    Anniversary Hunting knife

    In celebration of my 30th anniversary , here's a small hunting knife of my signature style. Blade of spring steel, diferential hardendend, lenght 14 cm, width at base 5.5 mm. Alluminium guard Handle made of palo santo and cherry tree with alluminium spacers and steel butt cap screwed and pinned tang. Sheath made from 5mm thick leather. I've etched the blade with lemon vinagar to give a darker look, it's not a blade with great edge holding like my other ones from file steel but one of the sharpest and strongest knives I've made yet. Still trying to figure out the right finish for the palo santo wood, the varnishes I use take days to completely dry. Cheers
