Claim 17:
18. The glass-based article of claim 1, wherein:
the surface is a first surface of the glass-based article,
the compressive stress layer is a first compressive stress layer extending from the first surface,
the depth of compression (DOC) is a first depth of compression (DOC1);
the spike is a first spike extending from the first surface of the glass-based article,
the spike depth (DOLsp) a first spike depth (DOL1sp), and
