Bronze and brass ornamental work spiral coils, and its rivet-heads (originally gold-cased) with whorls. Ordinary Mycenaean blades are enriched with narrow mouldings, parallel to the midribs of swords and daggers, or to the curved backs of one-edged knives. The spearheads have hammered sockets. Other tools and implements are oval two-edged knives, square-ended razors, cleavers, chisels, hammers, axes, mattocks, ploughshares and saws. Cycladic and mainland Greek (Helladic) weapons show no ornament but include some novel types. A tanged spearhead has a slit (Cycladic) or slipped (Helladic) blade for securing the shaft; and the halberd, a west European weapon, was in use in the Middle Helladic Greece.
Blittable types The following are some commonly used non-blittable types in the .NET framework: There are many more blittable and non-blittable types, and user-defined types may fit in either category depending on how they are defined (MSDN). This very restrictive notion of blittable types appears to limit the usefulness of the interoperability services provided by .NET, but this is not so. While blittable types allow a straightforward definition of interoperable types, various ways exist to explicitly define how a non-blittable type should be converted by the interop marshaler. For example, in the .NET languages there are many attributes which can be applied
