    Project 2 Munetoshi petty

    Step 1 - straighten the blade
    Issues/ Safety issues/ Screw ups?
    I don't have the skills to bend the knife by hand, so I went a different route.
    link:
    After following the instruction above, the blade still wasn't straight enough so I thinned the blade down.
    I will say the result is in between fair to good.

    Step 2 - Stabilize my own wood
    Issues/ Safety issues/ Screw ups?
    So I spend the past weekend playing around with the tools, I though I was doing everything right but somehow it wasn't turning out correctly.

    Then thanks to Milkbaby I realized that I purchased the wrong juice..
    I have reorder the Cactus juice, hopefully this time is correct.

    Step 3 - Cutting the dowel
    Issues/ Safety issues/ Screw ups?
    I didn't want to slow the project down while waiting for a week for the Cactus juice, so I went ahead and cut the dowel with a hacksaw.
    Overall I was shocked by how straight it ended up, very happy that I succeed during the first attempt.

    Step 4 - Line things up
    Issues/ Safety issues/ Screw ups?
    Basically prepping all the parts I will need for this handle and lining them up to see how things look.
    I made a decision to try metal, I know its not beginner friendly and I probably should get some rods in there.
    But anyway here we go, if it falls apart then I will go with something else later lol, the point is to experiment.

    Step 4 - Glue the bottom piece of the handle
    Issues/ Safety issues/ Screw ups?
    I am planning on drilling the dowel hole after this is completed, hopefully it won't fall apart lol.

    Unfortunately, unless you turn or carve green wood, Pentacryl doesn't have much use.

    Step 5 - Cutting pieces to the right width & Drill holes
    Issues/ Safety issues/ Screw ups?
    Everything are going pretty smooth. No safety issues and no screw ups.
    Pictures below are pretty self explanatory.

    Step 6 - Cutting pieces to the right length
    Issues/ Safety issues/ Screw ups?
    No issues, just parts being too long had to cut some length off.

    Step 7 - Line up everything making sure things are straight
    Issues/ Safety issues/ Screw ups?
    No issues, everything line up correctly so far.
    I am planning on adding 4 more metal spacers before and after each black spacing material.
    Once that is done, I will start glue everything together before shaping.

    At what temp did you heat the blade for the petty straightening process?
    Or did you just clamp it down without heating?
    I am thinking it might have screwed up the original tempering, meaning your carbon steel has lost hardness.

    To be sure to straighten a blade without interfering with the temper, I bend the blades using 2 wood sticks that have notches sawed into them. There are plenty of videos that show how to do it. Best way is to bend in a conservative way, check straightness and repeat as many times as necessary.

    Thank you for the advice! I forgot what temperature I used, but its the same as the guy doing the demonstration. I have tried to bend the knife, didn’t work as well so I figure I give it a try. Lol

    While 350 should be "fine" it's hotter than I temper many blades. A safer temp to use not to interfer with temper is using 150 c(300f) or 160c as a max. (unless you can ask the actual maker what temp was used.

    Gotcha, Thank you much for the advice! If I use 150C or 160C, would this process still work?

    You actually don't need such a super safe way for a laminated blade. They're super easy to straighten, one of their big benefits. I typically put them on the anvil and straighten with hammer, but that takes a bit of care. I would recommend three brass rods in a vice, or a straightening stick as described. heating the blade to 150 before bringing it out for the straightening is a little safer, but actually not 100% necessary on a san mai blade, as it will take the correction no problems even cold.

    Thanks again! Hopefully I will never have to do this again, but if I do, I will for sure take your advises as guideline!

    Overall I followed the same process as handle 1 for these two steps. The result was much better than the last run.
    Thanks to everyone's suggestions! Shaping the handle after installing the blade is for sure much easier and accurate.

    Handle #3
    I guess I got the bug. Woke up Saturday morning at 6 and finished handle #3 in a day.
    Very happy with the result, follow the same process as handle #2.
    Thank you all very much for the support and suggestions.
    As for now all three project knives I listed have all been completed.

    Hahahah Thank you thank you.
    Its probably just me being lazy.
    There are many improvements I need to work on; but at the moment I don't have much obstacles keep me from just making it work lol.

    Thank you! I am glad you had fun reading it.
    It’s more fun to learn while sharing it with the big family here. Got a lot of help and advices from everyone, that’s why things are actually getting done fairly smoothly!
    Big thanks to everyone again!
