I am Mar Jabagat. I design and custom made any kinds of Long and Short Knife. I believe that the secret with regards to Slasher Knife making is with the design of the "Blade". It is like the Kitchen knives. It has many kinds of style for different purpose. Examples are knife for chopping, knife for slicing, for fillet and etc. This is also the same as to the caliber of Guns in which different caliber creates different Damage.
