The first one is made by Kumar. You can search for him in Facebook under the name Vicious Tools, This knife is made using O1 steel. I believe now he has 1095, Elmax and D2 steel too, The sheath comes with the knife. You can check out some of his latest design in his Facebook page. Anyhow this is my first handmade knife. A word of advice, O1 is not stainless steel, so you have to oil it regularly or it will rust.
My pride and joy. This knife is made based on the One-Armed Swordsman movie. The steel is 5160 and the handle is made from kemuning emas wood. It has hammer patterns on the blade. Strangly I named this knife "Happy".
Another of my handmade knife, this one is made with IDK steel, and the handle is super special, it's Indian Rosewood.
If you look closely, you will see the same signature on both knives, the maker of these knives are Katz Tan out of Teluk Intan. He does not simply make and sell the knives to anyone, so you might want to get to know him first. He can be found on Facebook under the same name.
Those two knives does no come with sheaths. For sheaths, you might go for kydex sheath, Nadir from Outdoor Dynamics, based in Penang does kydex sheath. You can even send your blades to him if you are not in Penang.
He also sells an array of parangs under the brand MyParang. You can check out his website for more products.
