My first instinct is to iterate around each element in $PATH, glob it
[perform filename expansion], and then look for files beginning with k
as follows:

for dir in $(echo $PATH | tr ':' ' '); do
	echo $dir/* | tr ' ' '\n' | egrep "^$dir/k"

or probably rather more efficient:
find $(echo $PATH | tr ':' ' ') -name 'k*'
