Water jet cutting is about 2x-3x laser cutting cost. But it does not leave you with the melted edge that laser cutting does and I like that. You have too make sure you grind your laser cut edge back far enough so the heat treat process is not negatively affected.

Water jet is a high pressure erosion process. In time and consumables per blade plus wasted material, I can not cut out blades by hand and grind in profiles any cheaper than having them water jet cut. I usually have about 5 or 6 square feet of sheet for water jet cut.
