of from about 15 to 25 degrees from the work piece as measured in a plane containing the saw blade such that as the circular saw rotates a given tooth of the blade will rotate through the assembly 10 about 15 to 25 degrees of arc before it rotates into a cutting position against the work piece referring now to fig5 u2013 7 there is shown in another important embodiment of my invention a saw blade guide assembly generally designated 52 which as in the case of the assembly 10 of the previous example can also be used to stabilize the blade of either a band or a circular saw in the present example the assembly 52 is shown in use with a circular saw blade 54 a fragment of which is shown schematically in fig5 with saw teeth assumed on and around an outer peripheral portion thereof the assembly 52 includes an air jet saw blade guide generally designated 56 and a straight guide 58 fig5 only which may be similar to the straight guide 14 of the previous example the guide 56 can also be used in place of the angle guide 16 of fig1 u2013 4 and includes a base plate 60 containing a block 62 thereon the block 62.
