There is no female counterpart to Knight Bachelor. The lowest knightly honour that can be conferred upon a woman is Dame Commander of the Most Excellent Order of the British Empire (DBE), which is one rank higher than Knight Bachelor (being the female equivalent of KBE or Knight Commander of the Most Excellent Order of the British Empire, which is the next male knightly rank above Knight Bachelor). Also, foreigners are not created Knights Bachelor; instead they are generally made honorary KBEs.
Knighthood is usually conferred for public service; amongst its recipients are all male judges of Her Majesty's High Court of Justice in England. It is possible to be a Knight Bachelor and a junior member of an order of chivalry without being a knight of that order; this situation has become rather common, especially among those recognised for achievements in entertainment. For instance, Sir Ian Holm, Sir Michael Gambon, Sir Derek Jacobi, Sir Anthony Hopkins, Sir Elton John, Sir Michael Caine, Sir Barry Gibb and Sir Ian McKellen are Commanders of the Most Excellent Order of the British Empire (CBEs), as were Sir Bruce Forsyth, Sir Alan Bates, Sir Robert Helpmann, Sir Nigel Hawthorne, Sir John Mills, Sir John Hurt, Sir Christopher Lee, Sir Peter Ustinov, Sir Alec Guinness, Sir Richard Attenborough, Sir John Burn, Sir Michael Hordern and Sir Michael Redgrave. Sir Patrick Stewart and Sir Tom Jones are Officers of the Most Excellent Order of the British Empire (OBEs) while Sir Paul McCartney and Sir Richard Starkey (Ringo Starr) are Members of the Most Excellent Order of the British Empire (MBE). None of them would be entitled to use the honorific "Sir" by virtue of their membership of the order alone, but as they are all also Knights Bachelor, they are entitled to preface their names with that title.
Like other knights, Knights Bachelor are styled "Sir". Since they are not knights of any order of chivalry, there is no post-nominal associated with the honour. When the style "Sir" is awkward or incomplete due to a subsequent appointment, recipients may sometimes use the word "Knight" or "Kt" (note the lowercase 't', which distinguishes it from "KT", the post-nominals of a Knight of the Thistle) after their name in formal documents to signify that they have the additional honour. This style is often adopted by Knights Bachelor who are also peers, baronets or knights of the various statutory orders, such as Sir William Boulton, Bt, Kt, or The Lord Olivier, Kt.
Until 1926 Knights Bachelor had no insignia which they could wear, but in that year King George V issued a Warrant authorising the wearing of a badge on all appropriate occasions. The Knights Bachelor badge may be worn on all such occasions upon the left side of the coat or outer garment of those upon whom the degree of Knight Bachelor has been conferred. Measuring 23⁄8 inches in length and 13⁄8 inches in width, it is described in heraldic terms as follows:
Upon an oval medallion of vermilion, enclosed by a scroll a cross-hilted sword belted and sheathed, pommel upwards, between two spurs, rowels upwards, the whole set about with the sword belt, all gilt.
