    Earan,

    ano ang say mo doon sa mga ceramic knife? paano kaya gawing tari iyon.

    may nakita ako sa net...kyocera ang maker. magaan daw at matibay...can hold the sharpness 10x longer than any metal..
    ang problema 10x higher din ang price at puro kitchen knife pa lang ang nakita ko.

    ano sa tingin mo? (the expert ka dito eh)


    Regards

    Earan,

    How much is the cost of 1 cpm s30v knife? Only the blade, unsharpen, already shaped?

    Thanks.

    Sir Earan,

    Who is the best in the Philippines in this Craftmanship (knife making)? Do you have someone (knife maker) you could recommend who has the right tools and equipment?

    What would be the proper measurement to make a piece of knife for:

    1. Fork Knife

    2. Adjustible Socket Knife?

    Any idea of the D2 steel?

    Thanks for the information...

    Try sugbo_slasher he is one of the best gaffmaker as per my own opinion. He is also familiar with D2 metal. I ordered D-2 Gaffs from him... waiting for delivery palang...

    Just like Sir Earan he is also knowledgeable on metal composition, craftmanship and quality because he personally buy the steel, forge it and use it for his own figths.

    One more things bibigyan ka niya ng tips sa pagtatare...

    Re: Waht metal to use for making knife or Tari

    bullrider,
    with regards to who is the best knife maker in terms of craftmanship, i can't tell you exactly who he is. there are so many referrals (laguna/manila area) saying that these knife makers make for certain so and so (bigtime names). i haven't tried them all yet because of financial constraint. so far i have one qualified knife maker whose quality is satisfactory to me, and he is the one making the garol for me whenever there are customers who wants me to make their knife material (please see my gallery for sample).
    for the size of knife material:
    1. just to give you an idea 1"x3-3/32"x12" makes 5-6 blades depending on sizes. this is for fork knife.
    2. for adjustable socket, no idea yet. haven't tried them. i do have some design already but can't do it on production run since the garol will be formed by a mold die and it cost 5k, no budget for the moment.
    for D2, i know very well d2 steel because we use it as tooling material. its an old time reliable steel when it comes to impact strenght. i have here some cut d2 blades (around 40 pcs) which i made 3-4 years back. during that time heat treatment was done by ASSAB and they charge too much, 1.7k/kilo if i remember it correctly. until now i haven't set them in heat treatment. so i haven't tried them as knife material yet. that's all i can say!

    Sir Earan,
    Thank you Very Much!!!
    Let's say if I have this material measurement:
    5/8(w) x 3/32(t) x 12(L) or 18(L), how many blades could be produced out of this in fork knife?

    Thanks again for your answer.

    Re: Waht metal to use for making knife or Tari

    bullrider,
    if i were to made those sizes, approximately 4 blades (12") and 6 blades (18") and assuming that your blade will fit in 5/8" width. by the way, what is your blades material? and is it hardened already?

    Re: Waht metal to use for making knife or Tari

    ive used D-2 to make into tari blades. maganda ang talim at di madaling napupurol. semi-stainless ang D-2 kaya di ito madaling kalawangin. ayos din ang response nito sa forging.

    i suggest you bevel the edge before patigasin ang blade...hindi madaling i-grind ang hardened D-2. for want of a local source, wood planer (katam) blades are mostly made in D-2

    kapag tinabas nyo ang annealed D2, hwag kayo panghinaan ng loob kung animo mamon ito. try nyo i-grind...eeek...palaban. btw, mahirap pakintabin ang surface ng D-2

    Sir Earan,

    Am planning to buy direct from Admiral Steel the D2 and CPM S30V steel but i don't know how these steel are hardened. What do you think? Would it be feasible?

    Thanks a Lot.

    datasheet for D2 and cpm30v can be download online, heatreating must be done using a digital heatreating oven in order to get a uniform hardness and toughness.

    Thanks. Did they(Admiral Steel) hardened the metal or we have to do it outside to be feasible in knife manufacturing?

    itinatanong ko itong steels D2 at CPM S30V kung bibili ako from admiral steel ay uubrang gawing tari, at OK ang toughness at hardness na hindi na problemahin ng knife maker. i was thinking of the 3/32 thickness x 5/8 width x 18 inch length at minsan kc ay merong sale ang Admiral Steel. I was suggesting to my son in Jeddah to invest with KNIVES as his next project. Naka-latag na kc sa Pontevedra ang mga materiales, naka-paglagay na rin siya ng 4 channels CCTV at isang maliit na 500 sq meter lot sa tabi ng mga in-laws niya. Yong father-in-law niya ang ginawa niyang caretaker doon with an assistant.

    alam mo ba preng tsamp kung ano ang tamang sukat to build one piece of this Adjustible Socket Knife? mas maganda kc yong dalawang tipo ng KNIVES, Fork Knife and Adjustible socket knife para makakapamili hahaha

    Thank you pre and kumusta nalang sa iyo diyan..

    Re: Waht metal to use for making knife or Tari

    sa sukat pre ay hindi ko kabisado

    ang tinitigan ko lang sa materials ko
    ay yung thickness nya na 3 mm
    diamond back kasi ang mga atri ko at
    narrow lang ang blade
    kaya gusto ko sa bandang spine nya
    ay naglalaro ng 2.5 to 3mm ang kapal
    para hindi ako mabalian ng tari

    sa awa naman ay
    hanggang ngayon hindi pa ako nabalian
    sa materyales kong gamit
    HSS lang ang gamit ko
    na may halong cobalt

    marami yan dito sa gawing germany
    sa mga malalaking steel manufacturer
    pamputol nila ng mga bakal

    ang sa admiral steel ay nasa annealed form para madaling tabasin at gawin tari at ikaw ang magpapaheatreat ng bakal. si earan may alam kung saan ipaheatreat sa pinas.

    Re: Waht metal to use for making knife or Tari

    tari blades are small and thin enough to be heat treated without the use of temperature controlled ovens. heat the blade until bright yellow then quench in oil (i use brake fluid).
    when the blade is warm enough to be held in the hands..heat again until lead grey in color.
    let cool in air....try scratching it with a metal file...if the file slides...ayos na

    do not be surprised kung tumigas ang D-2 while grinding. D-2 is a cold-work air-hardening steel. but hwag magkompyansa so do the full quench treatment.

    Re: Waht metal to use for making knife or Tari

    bullrider,

    if you are planning to buy steel, i suggest you buy it direct from crucible steel, its much cheaper. i suggest you try CPM-M4, you will never regret this kind of steel. its one i consider top of the line from crucible. you will buy the hot rolled annealed condition. please see sample: http://i158.photobucket.com/albums/t...CPMplates3.jpg
    one thing that makes me different from the rest of knife maker is that i heat treat my blades using electric furnace. it can be repeated with same results. and its easy to adjust since i know what parameters has been used.
    cpm-s30v and cpm-m4 has been tested already since i have done a lot of heat treatment trials and i think i got the best parameters so far. for new materials, i need at least 9 trials for heat treatment to have good results, and its costly.
