Ooh! Well, my father bought me one; I still have it!

Mine is a 25-watt Weller with changeable tips. One's very narrow,
one's wider. IMO, 25 watts is plenty enought to fry ICs.

Well, the expensive stuff is very nice to look at (and to use), but my
father gave me this lecture about a voltmeter's internal resistance
(and why it's good to be a large number), and in a similar vein, why
an ampmeter should have a very low internal resistance. I remember
those two numbers are important.
