The blades should be corrected to 5.0cm for Penae and 1.2 for Poros. Planning to start making Penae in the winter. Please tell me what you think ab00t this drawing.



Out of curiosity - why the various primary bevels, and what does varying the bevels give you in terms of improvement of performance?




The different angles of bevels on the Poros is mainly intended to reduce the resistance gradually due to the immense thickness of 6.5 mm(goof on the drawing, not 6.5cm ) The accent is at the tip, all effort is done to give it enough penetrating power while maintaining intergrity. The 20 FG degrees edge is meant for slashing purposes, and the 25 degrees HG edge is done in such fashon to make some decent edge while retaining a worthy recurve and a steady spine. Added bonus is where the two cutting edges join, the point becomes a ripping maniac. The use of primary/secundary/tertiair grinds in this effusive manner gives the blades the ability to stab, slash and rip and maybe some (light) chopping. Being the pessimist that I am, the main concerns on this design is it's weight (won't be much left after all those crazy grinds, but never done any realy calculating) and difficulty to make. There's a good reason I nickname Poros Chimera Tetra, count the incooperated styles

And this takes us to the Panae, which I intended to make it a modified kiridashi, but instead it becomes a knitty necker. The 50 degree ZG at the tip is intended to make it a tough pryer/penetrator, and the 35 degrees secundary edge is intended to rough cutting and at last the 20 HG edge for finer choirs. The main feature on this rascal is the 2 tanto points!!! IMO the first tanto at the tip will make a smoothier slasher while maintain it's agressiveness as a tanto, and the second tanto, boy it's gonna hurt

it will be interesting to see these blades for real. the bottom one looks like it would be a fun one to grind. i'm still trying to figure out the top blade in the tip area. its an interesting design.

Wow, those look very interesting, I like the idea of the various primary bevels.
The Penae seems like an excellent self-defense knife, too.
Please keep us informed on how it goes:rockon::rockon:

Thanks for the kind words bros. At the moment, I haven't started with cardboard yet:o Being distracted too easy, and there are some semi-finished designs including a modified sheepfoot working blade.

As for the grinds, Penae won't be no problem, but for Poros:headbang::rolleyes: The "philosophy" behind these multiple primary grinds is to give the tip enough penetrating power and reasonable edge while optaining immensely thick stock. All my concepts are rather radical to the oldschool standard, but dreaming ain't no sin, right?

Micro, I got the Edit too:rockon: The Penae will both do well as EDC work horse and as last ditch backup. Note the peace symbol on both blades, they are part of my Hippie Killer series.

Too lazy to take some serious kickass pics of my 2008 annual Magnum:p

Cool. The big one kinda reminds me of a SigArms Pterodactyl. What are you gonna grind these on?

You are way off bro:p Never seen that one before. You should see the first scratches I made, it started as a regular recurve. As for blade material, I was thinking ab00t 440C or S30V. For the smaller one it won't be a problem, but after some consideration 440C and S30V will definitely be too brittle for the big boy. No worries, the big boy won't be made in the near future (10years?!). Plenty of time to choose a good steel.:rolleyes:

Obviously the blades are handle shape completely different. It just kinda reminded me of the Sig from the handle grooves and the spine hump.


Never seen that one before.

Most people haven't. Sig makes some quality knives from good steel but they don't market for crap.


For the smaller one it won't be a problem, but after some consideration 440C and S30V will definitely be too brittle for the big boy.

Depends on the heat treat. Paul Bos can make S30V pretty tough. A simple carbon steel or maybe A2 would be good choices also.

thanks for the tips, as for the proto I will use carbon steels because they're easy to work with. As for the spine hump thingie, I got most of the inspirations from Dietmar Pohl and R.J. Martin blades I have. The heat treat I'll have it done locally. The 2nd annual Dutch Knife Event will be in November, hopefully I will find something there.
