Preheat oven to 350ºF. Mix rye flour, all-purpose flour, caraway seed, sugar, baking soda, garlic salt and onion salt in medium mixing bowl. Add Crisco Oil. Stir with fork until moistened. Sprinkle with water, 1 tablespoon at a time, stirring until mixture forms a ball.
Divide dough in half. Place one half between 2 large sheets waxed paper. Roll dough 1/16 inch thick. Remove top sheet waxed paper. Cut dough into 1-1/2-inch shapes. Repeat with remaining dough. Place crackers on ungreased baking sheet. Prick each cracker 2 or 3 times with fork. Bake at 350ºF, 10 to 15 minutes or until crisp and golden brown. Remove to wire rack.
