Well sorry my bad english i was meaning sparks...

would leaf spring steel be good for making a big knife, it would be used for chopping wood and what not when I go camping. The spring is a heavy duty one from a ute if that helps. 55mm wide and 7mm thick

also how should temper it? or do you need to know the exact steel?

Don't worry, for a non-native speaker your English is very good

Jsr, thanks finnish is so different than english, its hard

Crna: mostly leaf springs are 5160 steel, its pretty tough if you do right grinding angles and good normalization, and differential heat treatment. I like to temper 5160 just like pure 0.8% carbonsteel, 200celsius and 1 hour, just put it in the oven. If you want extra tough 1 hour in 175c, then let it cool slowly and 135c for little over a hour

Ok thanks, im not sure about the angles i want it to look kinda like

[jakethebeast]

Just remember to make enough high angles, then it should be fine

[Crna Legija]

what would you recommend?

[jackssmirkingrevenge]

That is one sexy knife.

Hmmm...

[Crna Legija]

Id probably use this stuff because iv gotten pretty good with it, I redid the hard plastic parts of my car interior with it.

[jakethebeast]

Only material that im going to make blades is steel

[Crna Legija]

ohh yeah the blade will be steel i will use that to make it look


The fake carbon fibre is just for the grip up to the hand guard thing.

[jakethebeast]

yeah, i was just saying to JSR

[jackssmirkingrevenge]

yeah, i was just saying to JSR

I see your point, but dude, carbon fibre! My Mk.3 hasthis hanging off its end, wonderful bit of kit. I've never tried to work with it myself but I definitely want to have a go at making rough epoxy casts involving CF weave and machining them to a fine finish.

[jakethebeast]

but... knifes and carbon fiber.... naaaaaaaah iv always hated thos "tactical" knifes, the most "tactical" that iv putten to knife is cord wrap on the handle
im more to the traditional materials and methods

EDIT:heres one cord wrapped knife, picture is very bad, but the knife is in Australia ATM so its hard to get a new photo

got some more work done with the 5" knife. Yeasterday i fitted the upper bolster and soldered it in place, today i fitted the rest of the handle. The hadle is brass, red polypropylon, barked reideer leather, waterbuffalo horn and dark walnut.

This image shows the soldering of the bolster, this is before i filed it down



here it is filed down, ready for some more components!



And heres the fitted handle


from another angle (notice the riveted bolster, its the blades tang showing)
