Carbon Steel Gravers are suitable for use on most metals, wood, bone, ivory and onyx, and they are easier to sharpen than high speed steel. If you refer to James B Meek's The Art of Engraving he suggests than 90% of all scroll work can be done with the following engravers:

• Point graver No 4 will cut most scrolls, No. 1 for fine detail work.
• Knife graver, No 2 is for detail.
• Square is the most widely used and can be sharpened as a point, or chisel.
• Round graver, No. 50 and No. 54 are most useful.

• Knife Gravers: Preferred for line engraving and deep cuts. No. 2 is the most useful according to James Meeks, author of The Art of Engraving.
• Point (onglette) Gravers: Preferred for curved designs, scrolls, and fine lines. Favorites are No 1 and 4. (#1/0 smallest and #4 largest)
• Flat Gravers: Preferred for monogram backgrounds, block lettering and parallel engraving. Meek's favorite are 36 and 37. No. 36 smallest flat graver, No.41 largest flat graver.
• Round Gravers: Preferred for uneven surfaces, curved letter designs and shading effects. Meek's favorite are 50 and 54. No. 50 is the finest cut, No. 55 the largest cut.
Square Gravers: Square is probably the most widely used and can be sharpened as a point, or a chisel. No. 1 is the smallest square, no. 5 the largest.
• Tapered Lozenge Graver Preferred for fine work, script lettering. No. 1 is the smallest square, no. 2 the largest.
• Graver Handles: Seasoned high grade hardwood, turned and shaped for comfortable use. Half-head, mushroom shaped. 1-1/2" x 1-1/4". Reinforced steel ferrule for a firm grip on gravers and to resist splitting.
