I have compleated the knife on weekend and here is the spec and pictures.
週末にJPBK-β2、ついに完成! まずはスペックから。
Blade length刃渉り: 12.5cm
Total length全長: 25.5cm
Blade width (at bottom)元幅: 3.5cm
Blade thickness (at thickes)重ね: 0.5cm
Steel鋼材: Old file from Solingen. ゾーリンゲン古ヤスリ
Handle materialハンドル材: oak, brass pins ブラスピン、オーク
Sheath シース: oak オーク
Blade Profile: Diamond cross section / Scandi flat grind.
ブレードの形状: 断面‐ダイヤモンド・グラインド‐スカンジフラットグラインド。
When the knife is in the sheath, it will hold tight enough not to fall out, but I have added cordage, which will secure the knife even more.
ナイフを納めた時、シースから抜けない程度にちょうど良くはまるのだが、念のために抜け落ち防止用の紐を追加。柄に一巻きしたあと、シースに留めて使用する。
Since I am aiming at Japanese style bushcraft knife, I have added the fire steel to sheath.
I have made 2 holes for it, so I can use one for fire steel and other one for hanging some item like small tinder bag.
ブッシュクラフトナイフということなので、ファイヤースチールをシースへ。収納用の穴は2個開いてます。使っていない方の穴は、小さい火口袋などを吊るのに使えるかな?
Here are the shots with previous version.
前バージョンとのツーショット。
The system used for securing knife is different. The previous version uses the lanyard from the knife.
前バージョンではナイフのランヤードを使ってシースへロックしていたのだが、ランヤードは今回廃止。
The blade length is longer but the handle is bit shorter. Also the blade width is much wider now.
ブレードは長めに、ハンドルは短めに、刃幅も更に広く変更。
The handle profile is also different. The previous one was too straight till the end, causing handling problem when chopping in. the new one has stronger taper on the end, stopping the hand slipping through.
ハンドルの形状は前バージョンから大幅に変更。バットに向かって大きく広げてある。これでチョッピング時のすっぽ抜けを防ぎ、ナイフの重さを最大に活用できるはず。
the blade back has new idea. The blade is thicker on new blade, but has the profile of diamond. The old one has same thickness from back to ridgeline.
Also on the new blade, the tip side half of back has hardened edge with 90 degree angle. This is to be used for scraping job for crafting and fire starting. The bottom side of the back is not hardened and rounded. So will support the stress to blade and the rounded edge will be soft on finger when using.
刃の峰には色々と工夫を加えて見た。峰のポイント側半分は焼きが入り、90度のエッジが立ててある。これはスクレーパーとして、木の加工や、メタルマッチをこするのに使用。
ハンドル側半分は焼きが入ってなく、丸く面取り。削り作業時に指が痛くならないように、また、ナイフの強度を確保します。
I have been using this blade since first time the edge was put on. It has been put to batonning the oak to get the sheath material, whittle the handle and sheath, made few feather sticks with fat wood… and it is still shaving the arm hair, no eye visible damage on cutting edge.
I have really good feeling about this knife, and can’t wait to take out in woods.
熱処理後に刃付けをし、それ以来タッチアップさえ無しで、ハンドル、シースを削る作業、材料の切り出しなどに使ってきたが、いまだに産毛が剃れる。ショウジキ、ここまで刃もちの良い丈夫なナイフになるとは思ってもいなかったので嬉しい限り。久しぶりにワクワクするナイフを手にいれ、早く森に持ち出したくてしかたが無い状態です。
Man, you did a fantastic job on this one! Really. Everything came out great. Totally professional. I can't wait to see it at the Bushcraft Finland meetup.

I prefer the tapered sheath, but both knives and sheaths are ones to be proud of.

The tapered sheath is the new one and I also like the look of that better.
Really enjoying your blog. And that knife... Will you consider making one for sale?
