Abstract: A knife storing a fly-tying vice which is capable of securing a hook easily. The fly-tying vice includes two arms having their respective mouth pieces at one end for clamping a hook, and a main screw for bringing the two arms closer to each other and for allowing the mouth pieces to clamp the hook. A hackle-plyer includes a wrench hole being engaged with the top end of the main screw so as to turn the main screw for tightening. The main screw is turned lightly by hand, and whereby the hook is clamped by the mouth pieces. Then, the wrench hole is fit into the top end of the main screw and turned. Thus, a fly is firmly secured by the mouth pieces.

Abstract: Disclosed herein is an improved process for preparing 1RS-3'RS epimer of aminated phthalideisoquinolines represented by the general formula (I): ##STR1## wherein R.sup.1 and R.sup.2 are independently hydrogen atom or a lower alkoxy group, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are independently hydrogen atom, amino group or a lower alkoxy group with at least one of R.sup.3 -R.sup.6 being amino group, and R.sup.7 is a lower alkyl group. The improvement comprises, after having reduced a mixture of epimers of corresponding nitro compounds of the general formula (I) wherein the amino group is replaced by nitro group into the amino compounds (I), treating said amino compound at a temperature in the range of 20.degree.-100.degree. C. in an aliphatic lower alcohol in the presence of an alkali to epimerize 1RS-3'SR epimer of said amino compound into said 1RS-3'RS epimer thereof.
